my idea for a three-way crossover fic

so i've had this idea in my head for awhile now and i decided that the only appropriate site to publish it was here, so here's the catch of it.

after that Little 'Gabby Gums' Incident (watch the show if you want context) the CMC ran away from home because they felt unwelcome. then they ran into Wolf Spider and Vanitas who are two guys trying to find the Siege Parilous to get back home. they felt pity for the trio so they basically took them in

just so nobody gets confused this takes place in my universe so the characters might be OOC if that's okay with you guys

so what do you all think. should i publish it?
