Last-a-Foam OK? Maybe new parts with PVC and Vacuum Infusion?

I was working on my wing skins and getting the spars attached to the fuselage, and in general getting excited about assembling my wings. One of the wing skin layups had obviously parted company with the Last-a-Foam cores... Oh crap. That has serious implications elsewhere.

So I started searching around, and I found on this thread https://www.homebuiltairplanes.com/forums/showthread.php?t=2734 that Glasair had some issues with these foams, and that Orion is recommending that people not use it. And my wing skins are full of the stuff. I have some other issues that I am less than happy with in these wing skins too, so this is just the excuse to make my wife think I am nuts.

So, I am thinking in terms of making new skins on my molds using 3/8" PVC for the cores. I am even thinking of trying out vacuum infusion for these parts too. I took in Corsair82's session at OSH last year, and it looked doable when compared to my current vacuum bagging...

Whadayatink?
