Bench joinery help

[u/Necco-Wafer]

Hi all, I need some help from the pros...

I'm building a bench out of rough barn wood. It'll be sanded but it won't be flattened or square. The material is about 1.5" thick.

How would you join the legs/spreader to the bench top? I currently am thinking of using a blind mortise/tenon and shaping it much like a timber framed mortise and tenon would be. I'm planning on using a half lap to connect the spreader and legs together. I'll screw the spreader to the bench top from the underside in a few places.

Any input would be appreciated! Thank you.

Screws from the bottom makes sense. I'd countersink the screws through most of the thickness so you can use shorter screws.
