I could build the curve out of flashing and "great stuff" behind it,
that would take a good quantity of foam though.

If you're going to build up something out of foam, start with a base of
the beadboard stuff or decent quality insulation foam (pink or blue).
Then if you need something to adhere to the foam and flooring, use the
great stuff. At ~$4 a can, vs $8 for a 4x8 sheet of 1" beadboard (prices
are approximate and probably outdated) you'll quickly get more than 2
cans worth of foam for the same price.
