Flanking subs work just as well when placed inside as they do when set outside the mains. They just need to be a couple feet beside, behind and below the mains.
I'll send plans for the surrounds, and yes, kits include the crossovers.
Sounds like you're getting you system setup and dialed-in nicely.
