This router planing thing is interesting. I like your jig and will keep it in mind if the situation comes up. But I think you’ll find that jointing the lumber beforehand and getting a good dry fit before assembling will make things a lot simpler. I don’t have a jointer but I made a sled for my table saw that essentially does jointing. It’s just a long, stiff angle with toggle clamps to hold the lumber. It will take out a bow, but not any twisting so I’m just careful about lumber selection for projects whichI need that. I learned the hard way that a good dry fit is really necessary in terms of movement, especially on a larger top.
