Farm the various sea pops as my DRK, and once I have a full set, wait till a major LS is starting their run, and while they prepare, pop and kill the NMs, (and hope they dont steal my goldfish clone lol). I would possibly borrow a WHM to outside heal (maybe one of the ones that can't get a level up party due to everyone doing TP burns >.> <.<, yes I am still bitter even after all these years) during the JoL/AV fight.
I would also do the same with various other popped NMs, though only if its after the adjustments for the way the NMs pop, im not evil enough to go steal an ulli or a land god from back in their once a day repop days, though I might sell my service as a DD to linkshells that need items (after making sure they don't use bots, though that might be difficult given the number of LS leaders that received the banhammer after SE took out a major bot, which itself was after the salvage dupe banhammer, which probably took out a large number of people using payed for bots as well) after earning a reputation as being able to solo endgame megabosses.
Not sure if I would need to dynamis for currency drops if i was able to sell my DD abilities (because even without trust magic, ilevel 117 gear makes 75 cap era gear a joke), but I guess that I could help with dynamis lords for a cut of the currency, as killing it in seconds would give the level 75s more time to farm.
