201s are banned (except emergencies) east of Limerick Junction so that complicates power planning but may also limit axle weights on the wagons, presumably related to Cahir bridge? A 201-071 swap in Limerick yard during the necessary reversal there might solve the power limit.
Realistically this only starts looking economical if increasing track capacity Athlone-Portarlington-Kildare is deemed both necessary and expensive (Tullamore), and the option to push North Wall trains via a reopened Athlone-Mullingar line isn't higher up the cost benefit list (or precluded by a trail which I understand is on the cards)
