Farkas is skilled with one-handed.

Aela the Huntress is skilled in one-handed as well.

Onmund might make a good spellsword, I think he is skilled in destruction, illusion, one-handed and heavy armor.

I probably missed a bunch of other followers who match what you are looking for so here is a page that lists followers.
