Might not be that simple, with the modem holding set up details
Some way of storing user profiles, so different radios , sound cards , ptt options , rates and com-ports ,Calls can be stored for different radios
Would make changing from say HF to a VHF radio , without having to re-code the modem set up , much simpler

Decided not to peruse this path.
Too many moving parts... changing VarAC is one thing but also changing VARA modem settings is a hassle and it may break when VARA changes its configuration over time.
Better and safer to have separate installs for different configs.
