Is it feasible to have both? If so, have any of you thought about or
cobbled up a tail center that's outboarded from the tailstock or lathe
bed to support a swivelled blank? Perhaps a fixed #2MT on some sort of
adjustable shaft with the same curve as the rotating headstock or an
adjustable MT on a straight shaft?

Any ideas or suggestions? If not, I'll go quietly.

I think to have a usable tailstock it has to be attached somehow to the
headstock, if not it could wonder all over the place not providing any real
support. By attached it could be via gravity - but it's have to be really
heavy - it has to stay aligned with the headstock! No matter what!

But if you have a tall item you want to hollow, unless it is too large for the
swing of the lathe, turn the outside first using the tailstock (on the lathe)
then when you swivel the headstock to hollow you don't want the TS in the way,
but you do need a good (heavy, unmovable) tool rest.

Just my ideas
