I am just one person with a semi informed opinion…
I’d personally go for it. It’s an open cell foam, not very dense. I bet the laser will cut it easily. If I were trying this, I’d make sure I was cutting very quickly, speed 300, maybe 350, no lower. Foil can be melty and can be a fire risk, cutting very quickly is a good way to fight those risks, even if it takes multiple passes.
Also, with any material that is potentially melty or might burn, I’d stick to simpler designs without very fine details.

As per above about larger/simpler designs, I’d probably scale that test up to be an inch tall or so.
