I tried doing something like this awhile ago. The problem I encountered was that I couldn't disable the swap once the the device was removed, swapoff couldn't find the device path(as it wasn't there anymore) but the system thought the swap was still there. So plugging and unplugging the swap stick got my system thinking it had loads of swap. But I didn't experiment all that much, maybe there's a way. Tricking udev to hold on to the device node until swap is disabled might be possible.
