Seems to me it's not worth the trouble or savings. The cost of a new panel is not that much. Since you are remaking the ribs anyway, add the time cost of removing them from the old panel. Also, you have to remove the panel from the inner rim to put on new ribs. That's virtually impossible without doing further damage to the panel itself (if not outright destroying it). And it's probably already compromised by compression damage. Also, it limits you in terms of changing grain angle, bridge location, panel thickness (do we still want diaphraspasmic panels) etc., etc..
