You can also merit Formless Strikes.
Ah yes, since a Merited level 75 ability will work just fine in a level 40 cap.
I have altogether too much experience with Royal Jelly, personally. Vampiric Claws are an option, although camping Tres will require help, and is going to be come a lot harder around mid-next month.
Alternatively, as a MNK, you should have a /WAR sub, shouldn't you? Get the last 3 levels, maybe a few more, grab your AF axe, you're all set. Just have to keep some gimpy gear around for WAR.
That being said, I've done runs as a Dragoon along side THFs and NINs as the second DD, as well as a PLD. I've never done a MNK, and reminded people that H2H works horribly against slimes every time, but it may actually be possible if the second DD can keep up the slack and doesn't mind.
