I think that can be finessed by judicious attacks on the label area.
What I would be concerned about would be that the relevant data plane will now be stuck at 8600 MB for ever: however much you fail it over to nice big discs, it will use only this much of them. I don't know of any way out of this without rebuilding the whole volume (vol copy, or dump & restore, etc.).
