Is there data, or even anecdotal reports, of cosmesis or capsular contracture of a previously augmented breast after lumpectomy and hypofractionated whole breast radiation?  

So, you will probably encounter more people who admit to being abducted by UFOs than using HFRT in someone with a cosmetic or reconstructed implant.  I've even heard people argue that they go at 1.8Gy/fx as opposed to 2Gy "just to be on the safe side" with regard to capsular contracture.  ...
