Yes, this would solve the conflicts, but is this really handy?
Every explicit reference to a trait/class name has to be adjusted if the 
name changes or if there are any incompatible changes in the hierarchies.
Explicit references by names is probably always a solution, but not the 
best. The inventors of the trait idea tried to avoid it in favor to 
avoid the fragility introduced by it.

It would be a possible way, but personally I would not like to go there.
