What you should do is have the remote reciever have a VHF transmitter
into the VHF sides RX. What you do then is run the remote RX on the
opposite offset to the repeater. For example when the user wants to
come in on the remote, he switches to the + offset instead of -.
You would need to build a VHF repeater with a 1.2 MHz split, allowing
you to use commonly avalible commercial duplexers meant for 1.5 MHz
splits with a little less attenuation. Or run the transmitter into a
beam aimed back at the repeater and the RX on a Omni.
Although the Federales don't like auxilliary use on 2M, so you will
either need to call it a remote base, or transmit into your UHF side
instead and keep the VHF rx still on the opposite offset,
