Nobody I've asked seems to know the answer to this, so I'll chance my luck here:
What will the combined ScACC and MACC airspace be referred to as?
Will it remain the Manchester FIR and Scottish FIR/UIR both controlled from the same Ops Room, or will it become a combined Prestwick FIR/UIR?
The new centre is dubbed Prestwick as opposed to 'Scottish', but it can't become POACC as that already exists in the form of the Prestwick Oceanic Area Control Centre at ScOACC.
Also, what if the Dublin TMA goes to Prestwick under the proposed FAB?
Could a possible option be to mirror the Canadians who have their Gander Domestic FIR and Gander Oceanic FIR at a single unit, referred to simply as Gander Center? After all I understand that the ocean will eventually be in the new building also. (Swanwick is simply London Centre also).
Will it become known as just Prestwick Centre, with a Prestwick Domestic FIR and Prestwick OACC controlling the Shanwick OCA?
Not about to lose any sleep over it, just curious... but hey, what's in a name?
