If it was a system that I had some significant personal interest in,
I suppose I'd be willing to do things like that as a spare time
endeavor.  I've been involved in reverse-engineering projects of
comparable complexity.

If someone wanted to engage my services to do that on a contract basis,
for something that doesn't hold any personal interest for me, they had
better be prepared to pay a LOT of money.
