You might try the venerable i.vpoints in an xmon, then i.rectify.
The control POINTS file that that prepares (for the imagery group)
is essentially the same as what g.transform does for the wxGUI
georectification tool. The nice thing about i.vpoints is that
you can back-project an overlay of a vector map from the target
(to) location from within the source (from) location.

it can be a bit crunchy, but it works well.
