If you are low level you can do these one at a time, warping out after each one. I Found this out on accident.
Last year during the summer festival there was an event which put you in a random zone with a partner to find an invisible mog, it leveled you down to 1, but you were invis/sneak/deodor to all mobs. I accidentaly cursed myself looking for the mog, I had the cursepaper on me, but didn't think anything of it.
Some several months later I go back to the zone for dark knight flag. I was silenced by the "muter" this time. I didn't think anything of it, but then I remember the curse quest, but before I could get to the other one I was aggroed. I warped out, but upon talking to the taru taru, I was informed that I completed this quest.
So there you have it, even at level 1 with nothing you could "solo" this, it'll just take you two summers and a partner with some patience, heh.
