It looks really cool. I say go for it. You are one of the few exceptions of NOT doing regular, olympic-style front squats due to a legitimate limitation.
Although I have never tried it, I would say that it would probably take off some of the need for your core to stabilize the bar because balance will be much less of an issue. But that is just my ignorant assumption.
If you do not feel like it's meeting your standards, you can always stick to the back squat.
