Would they be able to remain part of the EU whilst being part of GB? Can it legally be done?

No they cannot. Even if they were to become independent, they would have to present an application.

Lots of machinations being attempted behind the scenes.

Probably not, I think all the possibilities are being explored but I think it would just be too difficult if these countries were not independent from the UK.
