Yes - I could see a heavy cut ending in many tears and bits of grinding wheel as the shaper is unlikely to be the first thing to give up....
I found a few pictures online - ranging from a mounted dremel, to the toolpost grinder style as you suggested, and also a wheel directly mounted on the motor shaft like a bench grinder.
I think the separate motor and spindle as on a classic toolpost grinder would be the most flexible, as it allows easy changing of the drive pulley to get the correct RPM for different size wheels, and the spindle itself takes up less vertical height.

If you cannot find a tool post grinder that is to your liking, I've seen tool post grinder plans using a laminate trimmer as the motor so you can achieve the necessary RPMs.
