Theoretically, and practical for small configurations,
yes.

IMHO, you can use any tool you want to compute some
"signature" for files you deem relevant.  But you have
to carefully consider the scalability problem, the
problem of false/negatives (how you/your program deal
with a modified file? bin/config/data/tmp file) and so
on. Tripwire (coorect me if I am wrong, but last time
I looked it was still to be updated in FreeBSD, focus
was on "aide") is a targetted tool that helps with the
information management... probably bloated :). Like
any tool, it is up to you to decide what's useful or
not ;)
