Expanding upon the medieval era and Medieval Overhaul discussion

[tomtomgra]

It always bothered me how quick and easy it is to go from tribal to the industrial revolution.
I currently use Research reinvented + Stepping Stones, but It still seems a bit dumb that I can go from being neolithic to having basic electricity.
Specifically I think the medieval era is ridiculously short - you are seperated by measly 2 research projects from having electric lights.
I've looked into Medieval Overhaul mod but from what I've seen it seems like a mod that doesn't fit well in a general vanilla-like playthrough.

So my question is: If you have used MO, what do you think and does it work in a normal RW playthrough or is it more of a total conversion?
