They did run full in summer peak, the clue being they operated three flights per day. My point being the use of one larger frame would be an efficient consolidation, am not suggesting a growth path here. Scotland has huge seasonal peaks and troughs to the US and this may be one way of managing this. Virgin have been in market for years, they just moved from one end of the M8 to the other, and Westjet aren't in the same league in getting to the US.
