An active setup is when we have a dedicated amp channel for each driver in the system, i.e., tweeters and mid-bass have own dedicated channel. Now, the XOs you have mentioned, though good would not and can not exceed the SQ outcome from Bit 10D. Once you pass the signals from bit 10, just get them flattened using a laptop and get the freq. curve as flat as possible (a tuner with knowledge of Bit 10 can do this). Then feed your drivers with the o/p signal from the Bit 10. Hear for yourselves and might be you'd be thanking me (just kidding
).
Regarding subs, I am not sure how they would sound together(good or bad) but each sub has a different sound signature and for this very reasons all setups that have multiple subs always go for same subs. Hope you have got what I mean.
