Idea is great +1
There was a lot of conversations about this. I came to this conclusion:

It's a bit complicated. Traditional arrangers (including the one you mentioned) in most cases are MIDI and newer ones have some audio. But the audio parts of the newer arrangers are "fixed". Meaning, you can transpose them somewhat, but they will sound same.

BIAB on the other hand has a kind of algorithmic randomizer. With different takes of same chording. You can have different variations of same sections generated. What I am saying, even if it is technically "possible", it doesn't mean that those random generated parts will sound their "best". It's like a lottery. Also the next time same composition might sound different.

The only likely way arranger is possible if PGM makes a new format for "styles" and manually selects segments for arranger parts, which they think will sound best for you, removing everything else. So basically it acts as a giant rompler, instead of generative software. Using existing method "as is" will cause if not technical, but musical inconsistencies.

I rarely (never) keep the first generation BIAB suggests. From experience, there are usually much better takes for certain parts if one is willing to give it some time.

P.S. If you have not used it yet, please explore the feature called "Partial regeneration" on any song that has Real Tracks, and you will see that some generations for parts will sound better than others. Arranger will not know that. Only you will.

I hope that makes sense.
