i´m guessing that if you use a glue that melts the pieces together, like ABS cement does, it should be fine. Whilst other types of glue will "let go" when heated up.
The only thing i found that may be a problem is depending on how you are gonna heat up your sintra. if you boil in water should work. but i have found that if you are gonna try to use a heat gun it may warp around the glue. Chemical / heat reaction? just my 2 cents. But I did some glue work also. keep us updated on your build
