One way to look at this is the parent bean factory is not controlled by
ModelGlue. It's expected this will be instantiated and passed to Model
Glue. (Look in ModelGlue.cfm)
Reloading the Parent Bean Factory is the responsibility of the parent
bean factory control mechanism. So, if you need to restrict access to
this, you need to do it in the location where you reload your parent
bean factory.
You may consider creating your new beanfactory in a separate application
variable, then switch it over when it is instantiated. But as it stands,
I don't see how MG can get involved with this process, because the
parent bean factory lives inside a different context.

The lock is exclusive and is double checked as is best practice.
However, I don't believe your parent bean factory is under that
same lock. So when you remove that bean factory, it's out of the
protected zone, thus problems arise, no?
Correct - the exclusive named lock only prevents duplicate
initializations; it doesn't do anything related to non-reinit MG
requests from accessing values/objects that are changing during the
initialization like the parent bean factory.
We need a method of telling MG to lock/unlock access to the parent
bean factory while we reinit it. An exclusive lock on the app scope
might do it? I don't know if that would be hard to obtain in practice
in production or if it would just cause a lot of timeouts?
