As for the 6/6A thing I'm surprised that didn't happen either. The X72 doesn't seem the "express" type, and follows the 6 for a bit (I think?)
It probably wouldn't happen, but if it did then they could make it so the 6 was every 20 minutes instead of half hourly, so 2x 6 and 1x 6A per hour.

Why would they increase the 6 (with a 6A) to everu 20 minutes when the whole point would be to reduce services?

The existing 6 would be cut to hourly with the 6A running hourly to replace parts of the X72, allowing the X70/X71 to run every 30 minutes rather than 20/40 as now. In turn, that would then allow then to coordinate every 15 minutes at Sunniside with a reduced X30/X31 running every 30 minutes.

X56 I doubt (unless some sort of link with Follingsby). X10 would need to be at bursting point to either consider re-increasing frequency in part or full, or re-introducing the X9.

47/47A would be the most likely candidates to displace older B9TLs.
