What you generally find is that different gameplay loops tend to clash in bad ways. Games with a bunch of moving parts also tend to be hard to nail down what’s working well and what isn’t.

To be blunt, this is an ambitious project, in a bad way. You’re approaching this as a large studio might and not as what you should be (which is as an indie dev).

Its age-old tradition for an indie dev to pursue their dream project and then crash and burn a bit before drastically scaling down the project scope, but I recommend doing a games more ‘game jam’ level before you undertake the dream project.
