There was that one Nord in Oblivion who was a master trainer in acrobatics. I wonder what you would say about him - that he should've been a Khajiit?

Aela's personality is very Nordish. She's proud and strong, and a part of a family-like organization. As for hunting, well, there are dozens of hunters running around in Skyrim, so you really can't say Nords don't occupy themselves with archery. Actually, I believe hunting is a very important part of their lives, since in this frozen land farming must be difficult.
That said, there should be more Bosmer in the game, so I woudln't mind Aela being one
