To join the Stormcloaks as a KHAJIIT!

I recently made a Khajiit character and as I haven't ever done the Stormcloaks side of the quests before I wanted to just try it out. And I can't just wait for my next character to do it as I'll be playing either an Altmer or an Orc next.
I'm all for role-play purposes of course. My idea was maybe she was raised by a Nord family or something along those lines. Or she just really dislikes the Empire for some reason? o_o
Any ideas or is this just crazy? BTW she's married to a Dunmer too. Hahaha... most random character I've made. XD
A Nord adventurer/bard, crossing the land of Tamriel discovered a Khajiit cub, homeless due to one of the many skirmishes between the Khajiit and the Bosmer. Feeling a sense of connection to this cub, he takes her under his wing, adopting her, teaching her to take a stand for what she believes in, the ways of the Nord culture, but more importantly- the ways of the world. Through these teachings, she learned to accept all walks of life, even if they didn't quite accept her. Her ability to see beyond the physical sense, she found love within a Dunmer. And because of her father's love and teachings, she joined the Stormcloaks. It didn't matter whether she was faithful to Talos or not. It didn't matter that Ulfric wouldn't let her kind live within the walls of Windhelm. To take away someone's faith. To take away someone's way of life... That was the true crime. These people are simply doing what her father taught her; to take a stand for what she believes in.
