For one, I don't think that someone who has completed chiro school way earlier in their life is going to have an easy time going to DO school decades later, content aside.... Secondly, if you haven't done it yet, why should someone "trust" you? Not saying it's impossible, it just seems baseless.
To play devil's advocate for these guys in terms of technicality - we say DOs are physicians, but they aren't viewed as such in all countries. Many countries still don't acknowledge DO credentials.
All this notwithstanding, OP, why do you want to go into medicine now? Especially osteopathic vs. allopathic?
