It could work, however you would be forced to instantiate a virtualized
class (probably a proxy?) for every class in every environment.
I'm hoping that this stuff will be shareable, so that e.g. in setting up a
new environment you can subtract capabilities from your current
environment by handing the new environment the parent (your environment)
and a set of deltas. But this is vague, very vague, because I still have
no idea of the Something that constitutes the environment and what a
parent environment would want to have for child environments in typical
cases.
Modifying the object format is an uphill battle, for good reasons, but
not one necessarily lost.
