Trouble is, of course, you are simply taking audio Parts from existing Event styles. Not creating something new. And they need to match the groove of the rest of the style perfectly, because you can’t edit them in any way.

Creating a brand new audio Part is daunting, to say the least. You need to record your player (hopefully someone of session player standard) playing at the very least a major, a minor, a 7th and maybe a diminished pattern in several keys (not really sure how many keys, it depends on how good the Event’s pitch/time transposition is). Probably at least six, so you don’t have to get the transposition algorithm to do more than one whole step.

Rinse and repeat for each Variation and Fill, then Intros, Endings and Breaks.

Phew…

Now bring in a drummer and a bass player.

I don’t honestly see how anyone with less than session pro skills is ever going to be able to pull this off.

We’ve been able to Frankenstyle (TM, patent pending, LOL) our arrangers for years. Bits of this style, bits of that. But brand new ones even using MIDI based arrangers was never easy. Add in having to record real players now, I just don’t see many succeeding. TBH, I doubt many will even try.
