[Advice] GPE to ARHD to GPE topic

Essentially want to end up with a nandroid of both so I can switch easily between GPE and ARHD.

Presently I'm mid 710000, supercid, unlocked and s-off.

Would these steps be correct:

GPE nandroid
Wipe
Flash ARHD
Flash firmware
Boot
ARHD nandroid

Then use nandroids to switch at will.

Question is will nandroids completely restore both ROMs including firmware etc? Particularity GPE so OTAs will still work.
