Gatorboard / Gatorfoam Revisited

I've seen lots of discussion about Gatorboard (a/k/a Gatorfoam) in the archives going back about ten years or so, but not much recently. Recall that it comprises the inner layer of Symposium shelves and is in the recipe for a popular DIY aluminum/MDF/foam isolation platform.

I'm trying to find a suitable material to support a 2" solid maple isolation platform on top of a 2" solid maple rack shelf. (I wouldn't use the isolation platform at all if it weren't for the need to expand the surface area of the rack shelf in order to accommodate my turntable. So, I'm not looking for much in terms of functionality or tuning or the like.)

Would a large piece of Gatorboard "sandwiched" in between be a reasonable way to separate the two maple boards? (They must be separated in order for the upper board to clear the "caps" that extend through the top shelf of my rack.)

It strikes me that this configuration, if the Gatorboard is almost as large as the maple boards themselves, may be similar to the DIY Symposium shelf -- minus the aluminum layers.

Thoughts on this, or suggestions on other ways to support the isolation platform?
