Any advantage of BFD w/ DEQ2496? & other ramblings

I picked up a BFD (1124) a while back for a project that is moving pretty slow, I have taken the BFD out of the box but never fired it up. I was recently offered a good deal on a DEQ2496. I picked it up because I was planning on using for my mains that I would like to build someday, and I am a "chump" (for the sake of the pottey police) for a good deal. I guess my question is:
Would the combination of these two components offer something that the DEQ could not do by itself?
I was considering selling the BFD but it is a relatively inexpensive piece of gear so it is not like keeping it will put me out much. OTO if the DEQ will do everything the BFD will do there is no point in me keeping it around.
It it makes any difference I am also planning on using a DCX2496 active crossover for my planned mains project. I have heard that it has some EQ ability but I have not looked into it. I only mention this in case it has any bearing on my original question.
As a side note, I know the DEQ can be easily setup to provide Linkwitz transform. One thing I did not like about the DEQ is that it appears to "only" be capable of 12 dB of boost (maybe 15). I would like to experiment w/ LT in a form similar to Bag End' s infra sub concept. I have Bag End 18 that that models an F3 of 50 Hz in a selaed enclosure. I am not sure how agressive Bag End gets w/ their EQ but to really push it I would like a little more boost capability on the very low end (if only for the purposes of experimentation). Will the DEQ still provide this or will I need the BFD to really get me some more boost potential? Bag End advertises "response" down to 8 Hz but if you do the math the amount of EQ required to get there is absurd. Of course all that EQ needs an absurd amount of power. Most of the powered 18's they sell that use this approach only have a 400 watt amp and I do believe that is what the stand alone subs are rated to as well. One look at the surround and you know that this thing is not going to win any displacement contests. No free lunch when you stuff an 18 into a 3 cubic foot enclosure and want to go low I guess.
I think it will be interesting to compare two drastically different approaches to the low end reproduction. One very tiny sealed box versus one very large infinite "box". I am very curious to see how both will perform with proper EQ.
Thanks,
