At the beginning I thought to create a separate package "SoundVMSupport" and put there the needed classes, but I discover that there are a lot which are needed. And moreover, all of those needed classes are in the category Sound-Synthesis. The classes problematic (regarding Project and morphs) are in the other package Sound-Scores. I have just tried and split the Sound package in two: SoundScores and SoundSynthesis. Then I changed ConfigurationOfCog to load SoundSynthesis rather than Sound. That works and I can now build the VM without problems.

My 2c: Just split of Sound-Scores into a separate package, leaving Sound containing Sound-Synthesis.
Other than that, it sounds like a good plan.

Why? Because it:
1. Makes it easy to still synch with the version in Squeak.
2. Avoids having to create a new baseline.
3. The extra work of either a), b), or c) is unnecessary.
