By the rules Jim has written yes Bonea should be able to do this. It was a shock when Bob animated the lion statue, not something we have seen before, he had only animated the Skull and Bob has also imbued items with magical energy for Butters.
Other disembodied spirits have drawn ectoplasm from the Never Never (Binders Goons, the Nightmare etc ) so there is no reason Bonea can’t, it is something the Fallen did when shapeshifting to increase mass, so she should have this knowledge but it is useless as a vessel because dawn would wipe it away, but using a vessel inside the construct would allow Harry to interact with Bonea in the same way as with Maggie. Just don’t hug her when dawn breaks. That’s the benefit of using skulls as vessels.
Of course if Bonea does it then Bob would be able to gain this knowledge, but without knowing his parents it is unclear currently if he has the knowledge to draw ectoplasm. His construct would look like Butters younger brother based on SG.
