I've been toying with a template that is similar, and it's been playable, and even somewhat fun.
I have slightly less ninjitsu, and have Archery and Anatomy instead of Wrestle and Detect. Pots/dog form/bandies helps for the survivability aspect. While the anatomy also helps the damage coming off my bow strikes.
All in all, it's a pretty nice setup. Never considered trying it with wrestling though. Usually when people see someone come out of hiding their first instinct is to get off screen to prepare for the fight. I like the range of the bow, but wrestle could be fun and have it's advantages also.
