RE: Can I use m0n0wall to merge 2 networks with different subnet?

In that case, Use the third nic to totally replace firewall B.  You will
have a line from switch B to Firewall A Nic 3.  It will be configured like
the LAN of Firewall B.  You will need rulls for that Nic as well. 
But routing will be solved.

========================================

IC, so that will be the last resort then. Is it possible that we use 2
firewalls so that we can keep the rules for Company B in FW B and rules for
company A in PC A?

I figure doing three NICs to replace firewall B would also require moving
all the rules from FW B to Firewall A. Because some users are allowed to
access internet, but some are not.
