I suppose one idea would be to get a couple of caddy bays for about a
tenner each at a TCR Saturday Fair or somesuch, then set the drive jumpers 
to CSELECT (Cable Select) and add, remove, swap around as needed.

That's somewhat clumsy but straightforward, I believe there are some caddy
type systems that effectively do the swapping bit for you.

Then there's the question of whether you're /really/ after a hardware
solution to this problem. Perhaps you just want to chainload one
bootloader from the other - allowing either disk to be the "boot" one?
