Subject: 3D printing PLA question

Does anyone have experience with melting away PLA?

BACKGROUND
A few years ago I was working on very small scale radio controlled
planes.  Weight was fairly critical and one approach to building
lightweight airfames was to take a old plastic model and apply tissue
paper directly to the fuselage as in papier mache.  Then after drying,
I'd slit the bottom of the shell and carefully remove the plastic from
the tissue paper.  Inevitably the tissue would crinkle but the final
would smooth out so it didn't look too bad.


THE NEW IDEA
What would happen if I printed a sacrificial fuselage out of PLA, then
applied the tissue papier mache to the printed fuselage.  The very
front of the fuselage would have a large hole and I'm imagining that I
could put the object in the oven and melt out the PLA.  The oven
temperature would be fairly low, like 200-300 F.  Does this seem like
a feasible approach?
