Gary adapter on A500

I have a memory expansion that uses a Gary socket adapter on the A500. I can't remember the brand name, but, it gives the A500 2 total megs of memory. I was thinking of buying one of those Kickstart switchers they are selling at Amigakit, but, noticed that it too has a Gary socket adapter, as well as the board that plugs into the ROM socket.

Can boards be piggy-backed on top of each other, so that I can continue to use my 2 meg trap door expansion as well as the Kickstart switcher?

Thanks,

Kirk
