Turning tons of Sandstone rubble into veneer stone

I have tons of sandstone rubble on my lot from walls that were built wrong by the previous owners.

I am planning on redoing the walls in CMU (Concrete block), using Footings and Surface Bonding Mortar. I am then going to split and cut the rubble into something resembling ledgestone or coursed ashlar veneer and adhere it to the face of the block.

My question is:

I have only a few pieces that would be large enough to cut into veneer corners. Could I simply miter a flat piece, wrap the corner and fill the joint with colored grout to match?

One concern that comes to mind is water may seep into the mortar at the miter joint and freeze, splitting the joint open.

Silicone?
