Modernize using existing doors?

DIYer looking to modernize these storage cabinets. They don’t get much use so not worried about wear and tear being a factor.

My idea was to flip the doors, rip them down to be an inset door. Don’t care about the current look being on the inside as they don’t get much use. Has anyone done something similar? Trying to not have to buy new doors and use the current ones. Would inset even be possible with the inner cabinetry set-up? Thanks for the help and ideas in advance!
