Alright! After cloning emuNAND to sysNAND I was able to succesfully launch sysNAND 2.1(although i did have to remove sd and re-insert at home to avoid blackscreen) I was then able to get my otp files (with correct sizes) And restore sysNAND to 9.2 and emuNAND to 10.7 using my NAND backups...
Thanks for the replies!

Yeah with the additional information Gerbil gave me I feel safe enough to give it a go. I'll use the method you described and will report back later :) If...
