Yes, I think so.
The product "DCWorkflow" (in the CMF CVS repository) does something
It modifies the role-permission mapping based on the current state.
Thus, it is maybe not yet sufficiently dynamic for you.
But perhaps, it shows you a way to go.
If it does not, you may look at "PermissionMapping".
This is a device that can map permissions to other permissions.
Almost surely, it can be made a ComputedAttribute and then
be completely dynamic.
