The assemblies you've listed are all using
[assembly: AssemblyVersion (Consts.FxVersion)]
consistently, so the assembly names are different.
The mentioned issues could be caused by a runtime bug, though.
Or by the Assembly.LoadWithPartialName and similar APIs.

This will break compatibility.

This is better, but then we need symlinks from lib/mono/1.0/
to lib/mono/x.x/ to help gmcs in finding those assemblies.

Just one probe:
$ gacutil -l | grep Custom
CustomMarshalers, Version=1.0.5000.0 ...
CustomMarshalers, Version=22.214.171.124 ...
They are different.
