I think that you might be able to create a simple LCD controller with the
X-Mega DMA controllers, timers and the event handling.

Yes, as long as we can set the outputs at 3V, regardless of battery
voltage.

If you need to cross voltage domains, and drive smallish LCDs,
a CPLD can be a good solution. They have separate supplies on IO banks,
and you can get them well under 10uA static Icc with 28-32 IO lines.
(eg ATF1502BE )

A chip like the xmega could provide the backplane(s) drives with
very little CPU overhead. (maybe none?)
(tho 44 pin xmega are a way off)
