Have you played the little bullet hell one in the steam vr lab? I wonder if that would work okay for what you're thinking. 
In that one the character you controlled took the place of your controller so it was in miniature. I thought it was a lot of fun could even add in a second controller for added challenge. Surprised I haven't seen anyone try the concept with toehoes. Would be a nice easy little vr gamedev idea. There are plenty of models that could be used.
