Why don't you try it and report back the result?
It's simple if tedious linear algebra, just write up the resistance
matrix, diagonalize, then read the result. Spice does that for you if
you feed it the net list. If you insist on doing it on paper, maybe
you should learn about weighted Mason graphs and how to reduce them to
elementary ones.
