Well it's definitely possible, the only question is how easy is it to implement
Best case: we can tag the existing bricks to be baseplates and have them count as such (baseplates in the engine's definition, as in they are attatched to the ground)
Worst case: probably a package of the function used to see if the hammer is allowed to break bricks (fxDTSBrick::hasPathToGround() iirc)
