Poor man's fibreglass on top of PVC

Hi folks
I clad a squaredrop with white PVC foamex sheets. It is retired now and has become a kids playhouse. But it's pretty ugly and PVC is hard to paint nicely. Would PMF stick on top of PVC do you think? An extra shell wouldn't hurt since it's not mobile any more... Any better ideas?
Thanks in advance
