Could you give an example which part of the language would not be doable 
with a moving collector? The only thing that comes to my mind is unions 
and that problem can be solved by allowing the user to specify manual 
scanning functions for structs or classes containing unions.

Also I don't think that we can create a GC which performs as good as the 
one of Java or C# if we are not willing to make the neccessary changes 
for a moving gc.
