My thoughts .. for winter hiking pants...
A separate outer shell - goretex or similar with full length water resistant zips on the outside of both legs. These would zip on over the to of whatever you have on as a waterproof layer, no need to remove muddy boots. Would do for summer as you can partially zip down to get more cooling - similar to pit zips. A storm lap over the zip to aid water resistance.
The inner would be just the thinsulate with an inner layer for ware. Not certain about a zipper on these similar to the outer layer, would be handy for quick changes. Don't know about a covering layer on these as they would always be intended to be under the goretex.
Having them separate gives you two options. And makes cleaning easier.
