Why not one piece? make the ports standard size, and leave material around the ports for end user fitment.
Since you don't like his design, why not try building something yourself, instead of complaining about what Andy's coming up with on his own? You already described what you'd like to see made.
I have made what I describe. That's my whole point. It is very easy if you have the equipment. From the parts he's shown, its obvious that he could make one.
I was trying to stay out of the selling aspect, but if someone needs one made just pm me.
All I would need is a couple of simple measurements for anything that is not factory deck ht.
