The more I read it, the more I think that your interpretation is a bit of wishful thinking on the part of the gentiles. Not saying no gentiles will receive the greater things, but at least in these verses the gentile role is to bring the things written to the remnant, that the remnant may be tested thereby. I would suppose that there are good things in store for the gentiles that fulfill this obligation! Have we? Are we?
I read it that the Gentiles [have been] were given the 'lesser portion' to test their ability to live the fulness of the Gospel. In the process, they will bring the knowledge they have been given to the 'remnant of Israel' to whom the resurrected Christ was speaking in those verses.
The numbers of the Sons & Daughters of Lehi who are baptized members of the Church in our area is staggering. There are 100's and 100's of 'Indian' names on the roles. They have 'stayed' themselves from full activity for any number of reasons, not the least of which has been the rudeness of the active Gentile members.
I do NOT flatter myself that my position before the Lord is superior. I am a genetic Mutt, thus a Gentile who approaches the Lord through the Gift & Power of the Holy Ghost. I am grateful to the Lord for 'numbering' me among the Covenant People.
NONE of us, Children of the Covenant and/or Converted/Adopted Gentile will receive the Greater Knowledge until after we have been tried and proven.
2Nephi 27
1 But, behold, in the last days, or in the days of the Gentiles—yea, behold all the nations of the Gentiles and also the Jews, both those who shall come upon this land and those who shall be upon other lands, yea, even upon all the lands of the earth, behold, they will be drunken with iniquity and all manner of abominations—
2Nephi 30
1 And now behold, my beloved brethren, I would speak unto you; for I, Nephi, would not suffer that ye should suppose that ye are more righteous than the Gentiles shall be. For behold, except ye shall keep the commandments of God ye shall all likewise perish; and because of the words which have been spoken ye need not suppose that the Gentiles are utterly destroyed.
2 For behold, I say unto you that as many of the Gentiles as will repent are the covenant people of the Lord; and as many of the Jews as will not repent shall be cast off; for the Lord covenanteth with none save it be with them that repent and believe in his Son, who is the Holy One of Israel.
3Nephi 20
14 And the Father hath commanded me that I should give unto you this land, for your inheritance.
15 And I say unto you, that if the Gentiles do not repent after the blessing which they shall receive, after they have scattered my people—
20 And it shall come to pass, saith the Father, that the sword of my justice shall hang over them at that day; and except they repent it shall fall upon them, saith the Father, yea, even upon all the nations of the Gentiles.
21 And it shall come to pass that I will establish my people, O house of Israel.
22 And behold, this people will I establish in this land, unto the fulfilling of the covenant which I made with your father Jacob; and it shall be a New Jerusalem. And the powers of heaven shall be in the midst of this people; yea, even I will be in the midst of you.
26 The Father having raised me up unto you first, and sent me to bless you in turning away every one of you from his iniquities; and this because ye are the children of the covenant—
27 And after that ye were blessed then fulfilleth the Father the covenant which he made with Abraham, saying: In thy seed shall all the kindreds of the earth be blessed—unto the pouring out of the Holy Ghost through me upon the Gentiles, which blessing upon the Gentiles shall make them mighty above all, unto the scattering of my people, O house of Israel.
28 And they shall be a scourge unto the people of this land. Nevertheless, when they shall have received the fulness of my gospel, then if they shall harden their hearts against me I will return their iniquities upon their own heads, saith the Father.
3Nephi 21
5 Therefore, when these works and the works which shall be wrought among you hereafter shall come forth from the Gentiles, unto your seed which shall dwindle in unbelief because of iniquity;
6 For thus it behooveth the Father that it should come forth from the Gentiles, that he may show forth his power unto the Gentiles, for this cause that the Gentiles, if they will not harden their hearts, that they may repent and come unto me and be baptized in my name and know of the true points of my doctrine, that they may be numbered among my people, O house of Israel;
