I'd imagine they would, rather than going to 5 digits. Didn't Arriva try 5 digits a few years back with the X-GGO darts, but quickly reverted back to 4?
Slightly off-topic - but the 5 digit numbers used on 1301-15 originally (and always on the never-used B6BLEs recently written-off) was a product of Arriva's Scotland West divisional management rather than the North East. The only 2 X-GGOs ever to operate in the North East with their 5 digit Scottish numbers were 1306 (X526 GGO) and 1307 (X527 GGO) which originally saw service at Ashington as 44016 and 44007 respectively. (Remember that they also were originally numbered 1501-1515 prior to renumbering to free the 15xx for Pulsars).
