Switching careers, looking to work MORE hours specifically

Can anyone please offer any realistic advice for someone who may or may not be over the age of 30 and is actually looking to work more than the bare minimum at a corporate job? Not only would I love an excuse to not come home at 5pm and take care of the kids and do dishes but I'd really like to make more money... My first idea was to move to the countryside and increase my commute by an extra 30-minutes. But now...

I've also noticed how my wife (and the interns) look at me when I'm dressed to the nines in my blue poplin Charles Tyrwhitt extra slim spread collar button down (100% cotton, btw) after working 50 hours and it got me thinking... imagine how they'd feel after 60... 70, even. 

I'm sure you're wondering how a nitwit like me got so tasteful with my clothing choice but it's all thanks to this forum. 

I regress... I'm desperate here, but I know I'm not working with much leverage. Here is an assessment of the situation: 10+ years of mediocre-to-dogshit-tier experience. Mediocre = Big 4. Dogshit = Industry. But, the last few have been at a P/E-backed firm operating in a niche sector and I suddenly have an urge to Actually Do Something with my time on the clock. There's clear opportunity to move into something better if I play my cards right. 

Note: I am not open to doing an MBA because I couldn't score high enough on the GMAT, I'm not financially capable, not really looking to be part of that whole "Yale" thing, and I'm already at a P/E-backed firm, which is basically adjacent to Wall Street's favorite exit op. Plus, the math just makes sense - working 60 hours a week means I'd effective progress 3x as fast as before so I'll essentially be guaranteed an MD slot in ~2-3 years, max. 

What options are available to me at this point? What would you do if you wanted to make more than $150k a year? Hell, I'd even be willing to do FP&A at this point. 

Suggestions?
