Mixing 4ohm and 8ohm


I'm upgrading my home theater front speakers, which will be used for 2 channel music as well, after 30 years. My current center and rears are 8ohm but the new fronts I'm looking at are Legacy Classic HD's or Signature SE's which are both 4ohm. (Love the Signature SE's by the way) My current AVR is a older Marantz 7010 which is switchable from 8 or 6 or 4 ohm. So, should I leave my Marantz at 8ohm or switch it to 4ohm? And, is it going damage it, or any AVR, running 2 different ohm speakers in the same system? And even if I were to buy a new AVR, which I will do once my Marantz dies, is mixing ohm's not recommend with an AVR? I have asked several sales associates but none of them seem to know for sure. I do know they suggest buying new 4ohm center and rears, buying different 8ohm fronts, or buying separates to power everything. I need the Audiogon guru's guidance with this issue. Your help and guidance is greatly appreciated.

Thanks for the info. I could go with new 4ohm center and rears but will my current receiver at 4ohms sound like crap? And any suggestions on a pair of 8ohm speakers for around that 6000.00 price range?
Interesting! So if I went that route I would assume all 2 channel (turntable and CD)would be powered by the stereo amp but would be controlled through my AVR? 
Suggestions on a stereo amp that would work well with Leagacy Signature speakers and my current Marantz 7010 AVR? Would like have enough power to open up those speakers but not break the bank.
