Ugh, what a disaster this route is.
I did get one EUA on a Weds morning flight back to EWR earlier this year. To be fair, though, I haven't given it much of a chance since I've been B/Y-up'ing or buying full F for most of the last two years on this route due to the rarity of EUAs.
I have to say, though, your chances look pretty slim on those route, IMO. Sunday you get all the folks scrambling to make the last of their weekends and get there for Monday morning. Friday, you have all the folks trying to get back home for the weekend. Can't recall a recent Friday flight, but the Sunday afternoon ones are typically packed.
Good luck!
