Well yes, is actually what i am doing too, currently helping Angelus to finish his Aegis (he on last stage, ~800 ordel left for full completion) as i did help littlechaos (amano) and cooncon (Gungir) also helping grimace in salvage for his mythic (i never take any alex, always give to him 4 free)

If you work out a system with your friends you won't need to tri-box. I can understand not wanting to impose on friends, However if they really are friends they should have no problem helping you. And if its a "I dont want them to help me with no reward" kind of thing, Do what i do, Help them build weapons too.
Well i was leading "twilight ls" for empy weapon and +2, i just ended to give up due to drama, they are still very good friend, just they not ready to spend that much time in abyssea as i do, and it was pretty much the main part of drama. Instead forcing them to come help each other (as it used to be) i just do everything on my own, at least i am no longer feel like i abuse of them. (or feel abused)

I guess you need to lead to understand it, all i can say is how we did spend time to help a friend, then that friend turned MIA after he get his empy done, but since i am the leader i have other friend asking me to help in return for the help they gave me for that guy that is no longer playing or interest to invest time in abyssea. So do the math, all i was doing is accumulating a help debt for trying help them, not going to hide it come stressful at some point, and i lost my mind and say, fuck all this bullshit, and left to do everything on my own.

I still help them no matter what, but not everyday as i used to do, and not for everything, in revenge i don't ask them to help me on anything. I feel better since that day, of course is way harder and could be way better with help, but just avoiding drama made 50 Glavoid shell 5x more easy to trio Box.

Anyway, story is a bit more complex then that, but you can see a good picture of it, i did H2H (full completion) GA (47/75 claw on last upgrade) and i have no debt to anyone, and just that make me feel better.
