Actually, satellite bounce seems to be much more difficult than EME.
While there have being several reports of ISS bounce, as far as I know
using a (smaller) satellite to bounce off and achieve a QSO has only
being done once:

This was done by 23cm stations well equipped for EME, one of them PI9CAM
using the 25m dish in Dwingeloo.

The path loss for satellite bounce is much better than for EME (-140dB
or so versus -271dB for EME in 23cm). The challenge is in pointing the
dishes, tracking Doppler (+/-30kHz during the pass) and the fact that
the radar equation considers only ideal conditions and in reality the
signals are much weaker and have QSB.
