NEC 1000 to 1100a Completed 2.4x-4x Can I flash to 1300a for multiformat?

I successfully flashed my friends 2.4x DVD+R NEC 1000a to an 1100a so now it supports 4x DVD+R writes, I have a simple question:

All the posts about the 1100a>1300 assume that the original drive is a 1100a, not a 1000 model, is there some difference between the 1000 and 1100 that would prevent me from turning the drive into a dual format burner?
