* Spelling as 量高 [iK] ?

In class today the teacher (in her 70s) specified that this was written as 量高 though that’s not found in the dictionaries (it is a legit, albeit non-jōyō reading of 量).
I got a few hits online for 量高 with かさだか, but it seems rather irregular and rare (the vast bulk of hits for 量高 are unrelated words as part of some compound).
If I see it written thus in print I’ll add it to the entry, but for now I’m just leaving a comment.
