Need help with table base design

I’m looking to build a new dining table. The plan is to have a solid cherry top, and some modern base. I’ve seen table bases made of steel tubing as shown in the picture. I want to make a similar design but out of wood (4×4). Has anyone done this before? The angles and dimensions aren’t an issue, but I don’t know the best way to actually join the pieces. In the steel table, there is a square plate that all of the tubes are welded to. I could potentially laminate a few layers of plywood, and dado the cross pieces into it, maybe even lag bolt into the side as well. Would that be strong enough? I want the legs to be sturdy enough so they aren’t going to flex or rotate once the table top is set on it.

Thanks in advance. Any help would be greatly appreciated.
