Yes, except the unsent messages and unreferenced variables, they can be
nil'ed using the substitution array. Example: many fields of Class(es) are
for use by the IDE only, just nil'em.

No. Spoon's dynamicity is not part of Hydra mitosis (and in order to add
it, Spoon must be added).

Yes: do transfer the corresponding method then put it [the method] to
work. "classic" Hydra can then load+run the saved .image as usual.
And if that .image also contains sufficient GUI,etc objects, even the
non-Hydra VM can load+run it and render it for your use.
