Checkpoint site to site vpn overlapping subnet

I am trying to create a site to site vpn with a 3rd party firewall.  The main problem is that my encryption domain is configured as and the 3rd parties is (so there is an overlap).  However, in actuality our encryption domain is actually only using ip addresses.  I can't adjust my encryption domain subnet as there areover 15 site to site vpns confgured and this would impact those vpns

How can I configure a site to site vpn given that our subnets overlap?  I found some documentation regarding making changes to my Checkpoint R62 user.def.NGCMP file (subnet per peer and subnet per range etc) but it seems a bit vague.  Does anyone have suggestions on configuring this outside of changing my encryption domain which is not an option?
