I really like the idea of theurgies

I just finished episode aigis and I think for p6 having a way of the protagonists personas being able to work together like the theurgies in p3 wiuld be really cool. Like special moves that maybe do a little extra damage or special debuffs. Having multiple personas is already really cool but them being able to work together is something that feels missing from p4 and p5. Is this a W idea?
