I reckon that's going to make it well tippy, slow you down (especially into a headwid) and without some serious fixings is likely to collapse at the first sign of a stuff, or rip your console out the deck if you fix it as per your sketches......
Lights & solar panels can go on the A- frame (as your lights appear to be already!).
As Biffer says, you could go down a super lightweight "cloth" canopy route. Someone has to have a ripped sail off a dinghy. (Assuming that photo has breen taken where I think it has!)
Failing that a baseball cap with a bit of string to attatch it to you is usually works quite well
