> I'll look like I'm trying to cover up a long period of unemployment on my resume

It depends on how you approach the gap in your resume. Gaps in a resume are not necessarily a bad thing. They show that you're human, and they can happen to anyone and everyone. I don't think there's any need for a cover-up here nor any justification as to why you were not perennially employed.

If you are applying for a position which is a good fit for your skill set and experience, and present yourself honestly, you should be fine.

I know people who quit great positions to start rock bands, sandwich restaurants, all kinds of things. Those side-projects can play into your hands if you approach with honesty and openness.
