I did exactly what you're talking about. It worked out very well. To minimize cancellation effects, I routed LFE info to the riser sub and front sub info to the main sub.
The driver is a JBL 2245H 18". It's flat to 23Hz with 6dB boost from an active filter. Power is from a bridged Adcom 555 (600W). It really adds a nice tactile sensation to the movie experience. You should go for it.
