Any particular reason you are insisting on dual opposed 12" drivers? Dual opposed 15s could work in that size box, or a single 18" and would likely outperform your current and proposed design combined.....
15s are not that much more expensive than 12s of the same family, which is the reason for my comment on larger drivers.
If selling your current sub is an option that might be beneficial, since mixing different subs is a bit of a crapshoot.
The Dayton Drivers are good quality drivers and perform admirably for their price.
Sealed is sealed no matter which direction the driver points. I assume your current and proposed sub are to be sealed.
Phase issues come into play if you mix ported and sealed and/or if the highpasses on the different amps have different roll offs which induce phase shift.
Again, not trying to convince you one way or another, just some facts.
Start a new thread with your design goals and link me, I'll help you with what little I know.
Honestly, if you want a dual opposed in that size performance range, buy this. You will not beat its performance for the coin and size limitations your talking period.
THIS fits your size, and a single one of these would out displace at least 4 sealed dual opposed 12s........ Although I would drop the port tuning to at least 20 which might grow the box by 2" in one direction, add some bracing and double the front baffle.......
