Importing and using my AVCS profile(s) for VoiceAttack will not mess with or interfere with any other profiles. That's not how I do.
Also, the AVCS4 BMS Radios profile requires AVCS CORE profile to be imported as well, as it is a framework profile I designed to include common operations relatively executed from within whatever game profile is loaded (such as AVCS4 BMS, or AVCS4 Ready or Not, etc.). You need to run VoiceAttack "As admin" through the options menu of VoiceAttack, if you get the warning that "database is offline" when loading AVCS CORE, but that's about the only curve ball. Everything else is quite intuitive.
First, download and import the AVCS CORE profile package, then download and import the AVCS4 BMS profile package:
