I guess it is in eye of beholder...
You would kind of limit yourself to "suggestions". I think it depends how it can be implemented.

I think I have another thought "inline" with this request. So you are in stylepicker and you like a guitar track or any other track, but you want to hear how it sounds within another context. Right click on it->Show all styles containing that RT(or RD)... So in theory, it should populate all styles that are using that track...

On side note, I can not stress enough, how important is to have more available tracks in the mixer. And should by especially useful for something like this. If more mixer tracks happen, you can audition 2 styles side by side within your arrangement, to see if they really play well together or not. Meaning, your first "style" can occupy first 5+/- mixer channels and second style next 5+/- channels. So you can use some or all RT's in that "suggested" style or hybrid. I am not trying to derail this thread, just mentioning this, because "suggested styles" is a good idea and if more mixer tracks will be available, I believe an item like this should be also kept in mind when developing.

For example, one way or another, you find "adjacent" / "similar" styles... To have an option to load RT's for that "similar" style to the next available mixer tracks, leaving intact what is already in place. That way you will have both styles in one mixer. I hope that makes sense.
