Clarification (if I take your meaning correctly): Flesh To Stone can't be Counter-spelled as it's Instantaneous; it is 'countered' by Stone To Flesh.

Earth To Stone, however, can be Counter-spelled or Dispelled as it's Permanent, which is a bit of a bugger if you're thinking of making building walls with it.

The 'Stabilised Earth To Stone' I added to the Construction spell school in my Yrth as a secret spell largely matches your suggestion here; same description but has Earth To Stone as a pre-req and is VH. Which makes it as rare as hen's teeth, which I wanted.
