Arrow [Q] For the Elite: Devs, this is right up your alley

Is it possible to write a boot script for dual booting NAND backups?

Let me explain:

I have 2 perfectly tweaked backups. One is 2.1 Firmware, and the other is 2.2 Firmware.

What I am asking is this... Is there a way at phone reboot to select which Firmware you wish to boot to...From there, a script would automatically restore the appropriate NAND file and then boot into that firmware?...

I understand there are ROM managers, but a NAND backup contains all the specific tweaks and settings and ready to roll at boot. So essentially, the only thing to ever have to be backed up would be SMS messages as everything else is self contained within that NAND file...granted you don't remove the apps from the memory card either.

I apologize if this has already been asked elsewhere, but I was unable to locate it.
