Dennis Hooker Sensei of ASU did such a pin in his Aiki Expo demonstration in Las Vegas.
I'll hopefully see him at the Summer Camp in the Rockies
. I'll try to remember to ask him about it then.
As far as people thinking this is entering into "jujutsu" territory, there are people out there who believe aikido is just a form of jujutsu. Besides, I'll say that I've seen a lot of stuff that people would say isn't a part of aikido done by aikido shihan (including self-retaining pins, pressure points, "small circles," kicks, sweeps, sutemi waza, and so on)...
