He sure does. All these inconsistencies could be explained away, if we are taking it seriously, or used in a crackpot theory.
By the way, your mention of Amroth reminds me of another possible candidature for Goldberry. And it is, of course... Nimrodel!

This maiden was surely strongly associated with the river.
She was quite likely fair-haired , like Goldberry.

A light was on her hair
As sun upon the golden boughs
 In Lórien the fair.

mmm ... what else?

Perhaps Tom lived with several Goldberries?
