That's certainly a more reasonable question.
I can't find this year's prize money online for some reason; maybe someone else can?
Last year (when the ECL was also about), EL group stage qualification was €3.63m, and each point was €210k (
here). The Conference League seems to be €2.94m for the group stages, and €167k per point (
here).
So let's say they get to EL groups and get one point - that's €3.84m. Five points in the ECL is worth €3.77m - so you'd be looking at 5/6 ECL points as being equal to 1 EL point, purely in terms of prize money. And ignoring extra gate receipts which you might get in the EL from presumably higher-profile opponents.
