Rumba leadership...

Let me start by saying I'm far from a elite rumbero, I do know the instrumental percussion parts and can sing a few songs.
This weekend I noticed a few guys, adjacent to the local "hippe" drum circle free for all, playing some Afro-Latin rhythms. So I quietly observed them play tumbao, with three guys playing two drums each for a while. Eventually, they went into a loose guaguanco, with two guys playing a two drum guaguanco, and two guys playing quinto all over the place.
I asked if I could play clave, and they welcomed me. After a few minutes, I asked if I could play cata for them, and they agreed - with one of the drummers now grabbing the calves. A few moments later I passed off the cata pattern to another of the drummers and started playing chekere and singing for a few songs.
After a bit, we ended the guaguanco and I thanked them and they seemed to have enjoyed where the drumming had gone - in a more structured fashion.
I bid my farewells and went on home. I have been thinking the little group had some potential for the development of a rumba practice or half-way decent rumba, but how do I tell these guys - who are 15 years older on an average - they got to ditch all the drums and play all the other parts?
It seems pretty egotistical for me to ask, but they did seem to enjoy where the drumming went.
Hell, maybe they' are just as happy to play every Sunday with no coro, chekere, cata, etc... And I need to go back to studying with my drum machine.
Any suggestions on how to bring this up with these guys without insulting them?
I know some serious rumberos show up there once every few months when there are no bembes going on Sunday and take over their little circle. It is just interesting because these guy just seem to play with no common goal unless someone takes over there scene and then they enjoy it.
I wonder why they don't try to create a rumba for themselves or use the time to practice seriously, instead of waiting for the rumberos to appear here and there.
I appreciated they let me get some real-time practice with singing, but I guess I see a potential for more from guys who are there every week, segregating themselves from the larger drum circle with Afro-Latin rhythms, but still being unstructured themselves...
