I'm not sure there is much point, but since someone raised the idea I think it's interesting to ponder.
Perhaps it would give you a more compact solution, space is an issue for some people?
Maybe it's just fun to think about. Why build a boat when you can buy an RTR cheaply?
The speed thing is interesting, my table saw is definitely 5,000rpm vs 3000rpm for the tile cutter.
Makes me wonder if there are different speed ratings for different saw blades (probably by size, lower for bigger blades) and what ratings my ad-hoc collection have.
But anyway, there are enough other issues to make it a potentially poor idea. (The endfloat of the motor is an unknown and there's no riving knife for starters)
