Manufacutred stone onto existing mortar

My wife and I have just recently purchased a new home. With the new home we have inherited a nice built in grill in the back yard. However, it is unfinished.

The previous owners had attempted to put a stone veneer on, but appear to have failed. The failure appears to be at the point where the went to apply the stone. All the stone for the job is there, and a few pieces have mortar on them.

By the looks of it, they have done everything properly up to that point. Solid concrete backer-board with a wire mesh over that and a scratch coat.

Instead of finishing the stone and leaving just the scratch coat. It looks like they used the rest of the mortar that was going to be for the stone and applied it with a stucco like finish.

My question is: How should I proceed from here to finish the job? Do I:
A: Continue with the proper mortar and stone (with possible acrylic adhesive) right over the existing stucco like mortar finish?
B: Modify the current surface to accept new mortar and stone?
C: Something completely different?

As long as the mortar is sound, you can go right over it.
