If you’re set on using a miter joint, you could do a splined miter. This is a miter with a captured spline to add rigidity and strength of the long grain glued connection as opposed to the splines going across the outside of the miter. This excerpt from Woodcraft shows the type of spline I mean, it’s something you should be able to achieve with a saw or small enough router bit, but make sure you have a fence setup with that to keep it stable and you safe during the cut.
If you haven’t, I’d recommend watching the Morton Jankel cut. It restores some cut scene segments and improves some of the pacing as well.
Technically not a single narrative, but the Mortise and Tenon magazine’s first three issues are bundled into a single binding. I didn’t subscribe to the magazine until much later, but I’ve enjoyed every article I’ve read so far over the last couple years. Green work is somewhat common in later issues, but may not feature as prominently in the first three issues as I thought at first.

The rocks change in a pattern, I swear it’s a single character substitution cipher! Wait a minute… “drink more Ovaltine” what the crap?
Objection your honor, this is obviously entrapment.
They look somewhat similar in design to the Japanese planing beam inspired sawhorses made by Len Cullum. FWW has a bit write up on it here:
