As far as a CR-V transmission for AWD, that would probably double the cost. I would need to rework the entire rear suspension: remove the rear torsion beam, build a sub-frame to support a fully independent system, new spindles, brakes, the addition of axles. In order to mount this, I'd need to remove the gas tank and fabricate a new one, because it takes up the space I'd need to mount the suspension. LHT does this, but I'm afraid to ask how much it costs.
