It's hard to know how popular Rovers B will be - a lot probably depends on the strength of the squad. The novelty value might be quite high, added to the general enthusiasm on the opening day, but if it's all U19s and lower FD standard players it might not be a huge draw. Same goes for the Rovers fans - if the A side aren't playing the same night, you might get a decent travelling crowd depending on the strength of the team. An away game against Longford on a Saturday night, if the A team are playing the night before or down in Munster, would be an attractive trip for a lot of people.
