would it look normal if a 6 feet tall guy movin on with a 4`11 girl ?

Why not? I am 5'11" and I have encountered some really handsome, well-proportioned guys who are about 5 ft. tall. If I meet my soul mate and he is that height, I would not reject the relationship. If he is confident that he can climb this tree and pick these coconuts, he can give it a try.

I think that the sexism & lookism that is prevalent in society really needs to be laid to rest.
