Can this swarm fly?

No bees can fly.

My limited understanding is that you may have a speaker set up that is amenable to a swarm set up. The swarm concept may be beneficial since it interacts with the room as the speakers that you are using. I look forward to hearing about your progress with this concept. Keep us informed.
 The sub that you are referring is not a product that I am familiar with, so I apologize for not having the information that you need. I have feeling however that something can be worked out with this sub in multiples. Just how many of them might be required I do not know. I suspect that the sub will have suitable adjustments built in so that it can be used in this manner.

Yes that sub will be fine. Tim, aka noble100 has been running a Swarm with his ML for some years and raves about it. As we all do. DBA is the best. 

One of the best things about DBA is its so flexible. It can be done all at once as Tim did, or incrementally, and the subs do not have to match. Mine for example is two sealed, two ported, and one active.  https://forum.audiogon.com/users/millercarbon
Original plan was to build the DBA and then sell the Talon Roc. Because who needs 5 subs? The four I built were indeed awesome. But then I brought the Talon back in and 5 was so much better I couldn't see selling it. I mention this to emphasize the point that with bass more subs is better. But money matters too. I would look real hard at the new DIY kit from Audiokinesis. But if it was between that and say 5 of the Dyanamos for the same money I would go with 5 over 4. 

In any case do not be swayed by the conventional wisdom that a sub has to be fast or matched or whatever to the mains. The conventional wisdom has it all wrong. For proof look no further than Tim, who has the Swarm and loves it precisely because it so seamlessly matches the speed of his ML.
