DIY table for kettle

So I'm kicking around the idea of building a table for my Weber kettles. I have a Smokey joe, the jumbo koe, as well as a 22.5 stand alone and finally, the 22.5 with the cart/table. I am thinking of building a table that would hold my two portable kettles (the 18 and 14in). I figured this would be a fun project as well as getting the smaller grills off the ground for when I'm grilling just a few small things.

Thoughts? Anyone have any plans for something like this?

I figured this would be a pretty standard table followed by a few circular cutouts with some type of barrier to avoid the hot grills burning the wooden table.

Thanks!
