Foam Core Floor Repair. Epoxy?

I’ve never had those type floors, but I’ve done a lot of difficult repairs on my TC that involved removing laminated structures down to a single inner or outer layer, then rebuilding what was removed. I’m pretty confident I could cut out the open area of that floor down to the bottom ply, then replace it with plywood that would preserve the height of the floor surface. I’d try to make the top ply patch even bigger than the plywood patch that would be replacing the foam that’s there now so the seams aren’t all on top of each other.

Are there ever any wires or plumbing running inside that type floor? Sure hope not.
