Most League of Ireland Clubs are made up mostly of part time players. The average club havs a working budget of about 500,000 and under. Budgets are very hard to determin since there is not information on the internet. These fugures are my guess. I know Sligo and Shamrock Rovers are closee to 750,000 however other clubs are well below 500,000 budget. The teams are just not willing to throw away a cash windfall the Champions League provides.
Then there is the FAI Cup and the IFA Cup. The winner of this will also punch a ticket to the Euro League. These cups become quite interesting and usually become the focus of supporters when the league title is out of reach.
The only way i see expansion is if it financially beneficial to the majority of clubs in both the IFA and FAI. Wound attendanc jump up that much to make the move. The Sentanta cup has shown us that attendance is lower than league games.
