Has anyone ever run a mystery with two unrelated monsters going at once?

Has anyone ever run a mystery with two unrelated monsters going at once?

I’m considering it for two reasons:

1. One of the player characters’ arcs / secondary story beats is going to come to a head when a bad roll at the right time opens me up to make a hard move and declare, “the stone in the ring cracks, releasing from within the old friend you thought was gone forever…” etc, generating a second ghostly monster that’s not a minion to the one already in play.

2. I have a large, unwieldy party. Usually a few people are absent, but there’s potential for up to 7 players. I feel like having two unrelated monsters (one planned as part of the mystery and one “randomly” occurring as described above) might be an interesting excuse to split them up and scale up the difficulty.

Wondering if anyone has experience with a campaign like that or thoughts.
