can I create a playlist that mixes my music and Apple Music?

Background:

I have 345GB of my own music (either ripped from CDs or downloaded live shows) organized in various playlists.

I have an Apple Music family subscription.

I'm not currently using iCloud Music Library.

I'm still using iTunes in Mojave, as I'm not at all a fan of the Music app in Catalina/Big Sur. (bring back the persistent filter!)

What I'm trying to do:

I'm creating a playlist for a party in a few weeks, and I'll be playing the music from a wifi-connected iPad.

Most of the music will be from the afore-mentioned personal library.

But I would like to add some songs from Apple Music that are not part of my library.

A) is that possible?

B) if so, how do I do it?

Additional considerations:

I don't care if my playlists are available in the cloud - I've found that the matching doesn't work very well.

I've read about some people having problems with losing personal files in the match/merge process, so I'm very leery of anything iCloud/library/music-related.
