Flavor Metal Core Wheels Got A New Gas Grill. Can I Toss In A Few Charcoal Briquettes On Top Of The Lava Rocks For Flavor?

Got a new gas grill. Can I toss in a few charcoal briquettes on top of the lava rocks for flavor? - flavor metal core wheels

Then my grill is damage or clog the jets of gas? I also thought about the implementation of the coal in a metal plate and placing it in the lava rocks. Please answer as I am with a cook on the weekend.
