26 y/o with B.A. in Communication, changing career paths to pursue MT

I'm a 26 y/o college graduate with a B.A. in communication looking to switch career paths and pursue musical theatre.

I don't have an extensive background in MT, but I do have dance experience as a scholarship recipient at a reputable studio (Cultureshock) in San Diego in 2012 and two community college performances where I played principal/lead roles in 2019. I'm currently attending dance classes and workshops at the San Diego Musical Theatre.

I'm considering formal MT education at university or conservatory as an option, and I was wondering if I have a shot at getting accepted into any of the big 10 MT universities? Are there any first year MT students who are returning undergraduates or other non-traditional undergrad students? Would I even be eligible for scholarships?

I'm wondering if a formal education is a good idea at this point... Or if I should just throw myself into NYC and take private studio classes as I audition... Not really sure where to find resources for my situation either as it seems terribly unique for MT--I am getting into the game quite late, haha.

I am positive that this is truly what I want to do. I'm just not sure how to get there at this stage in life.
