There can be a Mackenzie Calhoun and an Excalibur in the Novelverse, but they may not be exactly the same as PAD's Calhoun and Excalibur.

show up in Before Dishonor which is part of the Novelverse continuity and was written by PAD so they are PAD's Calhoun and Excalibur
Which is why I said there are times that the bubbles intersect. PAD's bubble intersected with the Novelverse bubble in Before Dishonor
