Ah, that's exactly what they're doing here (scroll halfway down the page)

Basically they heat up a piece of PETG in the oven then drape it over the
desired surface. Now I'd just need to find a source of tinted PETG at a
reasonable price (found 24" x 24" for $25...seemed a little pricey...must
keep looking).

Yeah, I tried that route but wasn't pleased as it didn't stay well and
bubbles were an issue.
