As Peter remarked earlier, the case with one 6LBR is more realistic than the case with 6 6LBRs for cost reasons. For the case of a single 6LoWPAN (one 6LBR), the PAN-ID discussion is not relevant as there's just one big LoWPAN.

but, it's not at all clear to me that this is a real use case!
Is the PAN-ID relevant?  is there one 6LBR or 6 of them?
