Don't bother with overshoes in the rain, in my experience they just make the whole thing worse on rainy days.
I just dry the wet stuff out over night/the next day and alternate bibs/base layer. Then wash all of it over the weekend.
Also helps if you can store uniform at work, enough for the week then just bring it all back at the weekend. That's what I try and do!
