Hi Ted and welcome to the forum.
It's nice to see some of the innovations that folks come up with, and it looks like you're a great customizer!
A very sensible approach to the daggerboard, testing it before making the final cuts. It'll be great to see what you end up with. No doubt, it will add stability as well as upwind performance.
How does your umbrella shade work out? Does it catch the wind? Looks like it may interfere with the sheeting while sailing though.
It will be very interesting to see how the jib performs and how you rig your Revo!
One caution -- be careful about using extra sail AND the Sidekick in higher winds. The Sidekick will limit the boats natural ability to heel and dump wind -- neither the mast or the mast step (sleeve) may be up to that much stress without some sort of reinforcement. Looking forward to your improvements!
