As long as it's no lower than the rest of the bike it won't be a problem. Very nice T.C. Iv'e thought about spraying my starter mat black to try and hide it a bit but your idea looks like a good plan.
Have to see how much Stretch would charge to make one , can look into it if you want mate. I have a spare he could copy off , Roosie paid over $200 each i think he told me ... he had 10 or 12 made up a few years back. I bought his last three.
