That is possible I'm sure. The functions may already even be there - just not used. I have an IKMOS rom that we've been meaning to disassemble, that would be pretty cool to port that stuff to an N52. We looked at IKMOS a long time ago and determined it could be used on any MSD81, cool that the N54 community figured that out on their own.
It doesn't take all that long to disassemble the file, what would take me longer is remembering how I did the tri-core specific stuff for it to work correctly. lol. And then of course finding the functions needed, and porting them to MSV80 (or even MSV70).
TBH this seems like something that might be better off as an open source project, as I doubt I will have time to do it by myself.
