I'm sure it'll be done once or twice, but this won't be commonplace, particularly for short robots.

The winch, I think, is the easy part: http://www.gearwrench.com/MagentoSha..._FRNT_MAIN.jpg

I agree that the longest part of the cheesecaking process would be locating it on the robot to align with the CG, though.
