I recently replaced my front speakers in my home theater system with a pair of Klipsch Chorus 2's and found that my Cerwin Vega Re-6c was a bit too under powered. So was looking at either the RC-52 or RC-62, Magnolia had only the RC-52 so decided to try it. Not sure if anyone has tried a pairing like this so just wanted some input.

I have the RC62 and love it.  to save a little money, get the RC35 which is the same as the RC62, just last years model.

The Chorus speakers are very high sensitivity so most center speakers cannot keep up with them.  The RC-52 is not a good match and the RC-62 is just a bit better.  Neither will have similar tonal balance.  You should try to find an Academy speaker as that would be the best match, though they have not been made for several years.  You can look at the classic section of this web site for details on the Academy.

There is even an Academy for sale in the Garage section.
