You could put a block converter in front of the VHF receiver.
Many years ago I heard of a voting system that used a number of VHF to UHF crossband repeaters as satellite receive sites. They all talked back to a hub location.? At that location they used a single UHF receive antenna feeding a preamp and a Down East Microwave block converter.? It converted from 420-430 MHz to something like 40-42 MHz or 42-43 MHz.? The converter fed a restive multicoupler that fed a number of low band Maxtracs and those fed the voting panel audio inputs.? I forget the frequency range, but i do remember that the multicoupler had something like 14 db of insertion loss...?? The reasoning behind this configuration was that back then 420 range radios were rare, but 36-42 Maxtracs and Radius were readily available and cheap...
I have no idea if Down East (or any other company) is still making block converters, but if so that would scratch your itch.
