Dual Sub-woofers paired into two sets of speakers - connection option.

I have 2 sets of speakers connected to my power amp A and B speaker outputs.

I also have two SVS SB1000 pro sub woofers hooked up to my pre-amp mono sub out with a RCA Y-splitter.

The subs have speaker level left and right input.

I would like to hear the supposed advantages of stereo subs.

Would it be feasible instead of using the mono sub out to connect from each speaker to one of the sub speaker level in inputs? Speaker A would go to sub speaker level Right input, Speaker B would go to sub speaker level Left input.

This way I can still switch listening from Speaker A or B and still have subs.

Would I run into any problems if I had both speakers A and B active at the same time? (I'm inclined to think its OK as the sub speaker level Left and Right are designed to both take a signal at the same time if hooked up to just one set of speakers).

I'm thinking I'm OK but I'm always overly cautious when wiring up something that is unusual.

Thanks in advance to those more experienced than I.

If your subs are powered, then the speaker level inputs will go to a line level converter before going to the sub’s plate amp. This will present a high impedance connection compared to your mains. 
 

Speaker A output to R/L mains and Speaker B output to R/L subs should be no problem.
 

Folks use dual mono subs driven off a sub or preamp out so they can position and adjust the subs to null out room nodes. For many systems this produces better results than true stereo subs. Lots of reading on this subject is out there.

A another consideration is high passing your mains to 1) better integrate with the subs and 3) take the bass load off the mains. I use this approach with great results.

good luck and enjoy
