It could be, but I doubt it. Hoster was still in the field after the Battle of the Bells, his bannermen were present at the Trident, and it would be very strange if Northmen and Valemen were left behind rather than Riverlords.
In relation to the number of the rebels at Trident it could be at Hoster conviced the remaining Lord Paramounts to mantain part of the army at Riverrun to protect the western riverlands of a Lannister attack while their marched to King’s Landing?
