I play Imperials, I am so to say playing Trooper Tank + 3 Jedi Consular. Your setup looks good. 3 Jedi Consular may be easier since you dont need to watch energy bars of your DDs then.

Generally I'd say you cant multibox with 4 toons:
Operations
Directive 7 FP
Foundry FP (dont know whether this is Imp. only)
