I'm not sure what the answer is, but the existing setup worked for 10
years. What did they do 10 years ago that you cannot do now? If you
can duplicate it you will save a lot of money.

Does it sit solid with no seal? If so, can you buy a thinner one or
shave a wax seal?

You could get a piece of 1/4" treated plywood, cut it to fit the base of
the toilet. Then cut a hole in it to fit around the flange. Align it so
it's exactly where he toilet will sit, put a few nails or screws into it
to attach it to the floor. Then mount the toilet in the usual manner, on
top of this plywood.

You're toilet will be 1/4" higher, and you'll see the edge of the
plywood around the base of it, but it will make a good seal and save a
lot of expense. Some white caulk should hide the plywood edge pretty
well too.
