Any pathway from big 4 to ER?

I’m working in big 4 capital market and accounting advisory team as a senior con, about to get promoted to manager and thinking of my way out from Big 4 to ER (if possible). I’m a CPA with master of accounting and an MBA. should I target for entry level ER programs? any possibilities for more senior role? I’ve got a finance undergrad degree and am a CFA level 2 candidate. any ideas welcomed!
