I have a gig tomorrow night and my RG7620's 5-way switch has died.

I searched the city and was only able to get a Strat-style 5 way switch, not a megaswitch. Obviously this is not ideal but I need to get this guitar working somehow.
What I have appears to be the same as the Stewmac layout here:
Is it possible to wire this to have the same pickup settings as the RG7620? (
wiring diagram here

If so, is anyone able to crank out a diagram for me?
And if not, is there any way to at least have Petrucci-style wiring with this switch? I don't usually use the 'both humbuckers' or 'neck humbucker in parallel' settings, so if I can at least have the neck humbucker,
bridge humbucker, and combined single coil sounds, I can get through the gig while I wait for a new megaswitch.
