Should this also be used for Co-Principal Investigators?

I recently created an entity for a similar role — co-principal investigator (Q106648356). My thinking is that the roles are similar enough (as opposed to a deputy principal investigator (Q105834068)) and that multiple Co-PIs can be added as principal investigator (P8329). Is that the best way to do it, or should they be added as a participant (P710) with the qualifier stating that they are a Co-PI as I did on this entity? Thanks!
