Sub Pre-out To Filtered In, One Scenario It's Okay?

I understand all the reasoning typically against this setup. I just wanted to question this particular scenario.
Maybe this has been asked before, but I couldn't find this exact scenario by searching. Sorry if it's a repeat.
Using an AVR for pre/pro. AVR only crosses over at 80Hz. I have Lsi15's. I'd like to use sub only for say 70Hz or 60Hz and below yet I want the ease/flexibility of turning the sub off/on via the AVR menus (no need to walk over to sub, I'm lazy
). I also don't want to buy a bass-management component or new processor (no money at the time).
Anyone have an argument for NOT setting fronts to large, sub on, sub pre-out to filtered in on sub, and dialing sub-crossover to 70Hz or 60Hz.
Just figured 80Hz and below will be sent to sub, then sub-crossover can cutoff at 60 or 70 and I'm assuming there will be no frequency gap since Lsi15's are set to large so they should be getting the full frequency.
Basically this will allow me to just add some extra low-end bass if desired by turning on the sub.
Please let me know if you see any arguments against it.
Thanks!

Oops, sorry. I think I just answered my own question by running some tests.
If you have other speakers set to small, mains to large, sub on, the LFE is not sent to the towers and sub for the speakers that are set to small. When the sub is turned on in AVR, for speakers set to small, the LFE is only sent to the sub (at least my AVR).
So in summary, I would lose the 60-80Hz range for the centers and surrounds.
Sorry for wasting your time with the reading
