Yes, you can do it and w/o any glue - the version of the assembly is a part of the name, so the assemblies are in fact not named identically. Only the files are and they can be either in GAC or in a different subdirectory of your app. Your App.config can specify subdirectories used to look for assemblies [1].
To choose the namespace/class from one assembly or the other use extern aliases [2] in your code.

Maybe we will need some tricks to solve the reference problems - I don't know whether you can reference two identically named assemblies containing identically named classes from the same C# dll, even if they are signed differently. But I think some kind of glue layer dlls could easily solve that.
