That doesn't violate the words of Christ. This very well could be the preincarnate Christ.
But supposing for a moment that Moses did meet with the father and with Christ, do you believe that Christ and the Father would have different wills? Isn't the will of the father the will of the son?
Or not. And that's the point -- there is no justification for your confident assertion that Christ was the One who spoke to Moses and Aaron. More likely, it was not. The nature of the Trinity is that it is three distinct persons, Who manifest God in very different ways. The Scriptures generally don't speak of the God with Whom Moses spoke, in the sense of Him being Jesus Christ of Nazareth.

No, their wills would be the same; but it does not follow that you properly understand what their will is.
For example, Jesus was quite clear about what defiles a person -- and it wasn't food of whatever description. For you to go back and say that "Christ" said differently in Leviticus, is to put these two passages at odds with one another. Jesus' point about the Old Testament is that the spirit of the Old Testament is what matters: the law and the prophets are summed up by "Love God and Love your neighbors as yourself." To reduce those two commandments to ritual food laws and such is precisely where Jesus found fault with the Pharisees.
A theological distinction has long been made between the moral laws of the Old Testament, and ceremonial or practical laws such as those related to foods or fabrics.
I strongly suspect that you have yourself made such distinctions between moral and ceremonial laws ... or do you actually follow the rituals described in Leviticus 1 -- the bull and the lamb, and the sprinkling of blood on the altar and the burnt offering and all that?
It's fine with me if keeping certain laws helps you to remain faithful -- I certainly won't try to talk you out of them. When you try to convince me of your position, though, I reserve the right to take exception.
