Sounds great man, that's my standard approach to things! But yeah, please let me know how yours work out when you get a chance, thanks!
A couple that I've been thinking about (if feasible) were something like:
JF 59RR
CH 1 - JMP voiced w/ gain stage selection
CH 2 - JCM voiced w/ diode clipping switch
Salvation Stonerverb
CH 1 - Clean or maybe Raw side
CH 2 - Dirty w/ noise gate
Anyway, I have very little hands-on experience with most mods out there, so these are just some ideas I've been mulling around based on samples I've been listening to....
