I agree Rmac that one can discard the published MEAs "due weather" - I remember transiting Germany once at FL080 keeping just below the freezing level, IMC (and icing) all the way otherwise. They didn't like it but let us do it.
However I don't think this is a good IFR strategy, because down below the cloud you have severely limited options in bad weather. Clouds have a habit of lowering and before you know it you are back in the muck, and if CBs are forecast you are back in the risk of going into one. I'd rather be on top where one can see for tens of miles and be ahead of things.
