I have 2 pair of front speakers: 1pr Boston Acoustics VR-M50s and 1pr Energy e:XL-26s. I bought the Energys off craigslist before I ran across the BAs on ebay while on vacation far from home and picked them up and flew them home in my suitcase LOL (I've wanted a pair ever since I heard them at a friends house years back).
Currently I only have the BAs hooked up with a Polk center channel.

I want to upgrade to 7.1 (on a modest budget ~$500) by adding 4 surround speakers and a sub. Though honestly I'm pretty darn content with the bass put out by the BAs with no sub!

Option A:
Buy Energy Take Classic 5.1 (cnet editors choice). In this case I would replace the Polk center with the Energy center. Would these speakers be mismatched with my BA VR-M50s? The Cnet reviewer raves about the match between this sub and surrounds.

Option B
Buy Polk OWM3s (4) and PSW110/125. Would these work better with my BAs or my Energys? These Polks look like they could be discretely mounted which is a bonus for the wife.

Option C (which my wife loves - since we might move our TV to a different wall someday)
Sell the BAs and the Energys and get a Polk Soundbar50 or Definitive Tech Mythos SSA-50.

Thanks for any advice you can give,
