Congrats on the Compass. On July 18th, got my wife a 2012 model. We are also loving it.
The front wheels will fit, if barely. According to this thread
(thank you Gramps), about the largest tire/wheel combo you can get onto a compass is a 29" or 29.5". The front 2010 SRT8 wheels are 29 inch wheels/tires overall, so they may fit. The rear SRT8 wheels are a different size, and are 30 inches. They may not fit, as thats a bit big.
Keep in mind... this is a comparison of the overall diameter, not the bolt pattern, rim, how the brakes would take the extra abuse of a 20" wheel, etc. etc.
