Angled stretchers

I picked up a pretty piece of green marble at a yard sale for really cheap. It's 31 x 17 x 1.75. Nicely polished, green, curved front corners. Weighs about 100 lbs.

The goal is to build some hefty legs under it.  Either 4 or 6, haven't decided on the layout yet.

But because of the shape some of the angles will not be at 90 degrees. I'm wondering about the best way to attach the stretchers to the leg tops. My first thought is a block behind the leg that would attach to two stretchers plus leg top, using hefty wood screws. Then an angled tenon approach for the non-90 degree stretchers. Would add more of a reveal than the pics indicate in order to give the tenons enough depth to do their job.

Any other concepts come to mind?

I believe most counter top installers use silicon adhesive to hold down marble and granite counter tops. A good bead along the stretchers would probably hold it. No experience, just a suggestion.

I read your question as asking how to attach the stretchers to the legs. If you are good with a handsaw, you can cut angled tenons on the stretchers and then cut a mortise into the leg. Google angled mortise and tenon and you will find examples. If you aren’t a purist, pocket screws would work fine.

I cut angled tenons at the table saw with a tenon jig and dado stack.  The angle is set on the jig rather than the blade.  Doesn't work the other way 'round.  Fast and easy.

Maybe make the legs non-square? Rip them at angles that allow the stretchers to mate square to the face of the leg.

Without my Domino I would resort to pocket screws & glue & the angled braces you drew in red plus one beside the front leg straight back.  Small dollops of silicone will hold the stone top in place.
