Your idea should work out fine for the purpose you intend. If you feed the condenser side ground source water, that would improve efficiency by lowering the discharge pressure. Once you commission the rig, you will get a better idea of the factors at play. Lowering the Delta T just a few degrees can improve your energy savings a substantial amount. Plus, you can dig further into freezing territory without shutting down the heat transfer.
With a custom made system, you get to do all of the testing and measuring, so the sky is the limit as to the potential for savings. It just depends on how much you want to spend up front on the design.
