Looks fine to me. But obviously you know your domain.

If in future you do need to migrate to different types then that is a data migration exercise. And can't be avoided. But if your data model is correct then you shouln't really have a big problem.

If your data models are wildly different then that will be harder.

One final comment, consider using optional aspects as well as mandatory ones.

I don't see how migration is possible. If I decide that Type2 should be split into new types: Type5 & Type6, is that possible without downloading all the data and reloading it?
