I believe that the OP intended to use a VL for each SD-card? And possibly overlapping VLs? Then it should be feasible to connect to a SD-card, select the VL for that card, open the card as a device in calibre and send books that are missing to the card, or delete books on the card that no longer are included in the VL. But I am guessing...
I assume that the tablet is only intended as a reading device? If that is wrong then disregard everything I say here...
It would most likely be easier to do slightly reduce the size of the library to copy, so it will fit on a single 32 GB SD-card.
I have around 4 000 books on my Xoom, and it takes less than 10 GB. Plenty for me, and room to grow.
