One of the things I always try to remember to do, is try RTs that were NOT part of the original style.
I have some cool stuff (to me anyway) that combines things like Grunge and Bluegrass and Funk.
Chances are few have used that particular combination, but doing so taught me to make the effort to experiment with RTs I normally may have ignored.
Grunge drums, bluegrass banjo/mandolin, and Funk bass .. I still play it once in a while to reinforce the message.
I think it may even have Mason guitar solo RT for a section .. point is, experimenting often makes you realize stuff you didn't think you will use is suddenly seen in a whole different light.
I'll see if I can find the link to the reference above; may not fit your taste (which is why I haven't found a real life use yet, I suspect a pretty limited taste palate would enjoy this like I do) but it shows how the many seemingly unrelated RTs can indeed play together nice.

Sure it's weird, but they all play together

I do not work here, but the benefits are still awesome
