Great suggestion! I took off the middle ring (48t) and replaced it with one of my rings (40t) from the timing chain just to see if it worked and it does, no more rub while trying to go to the big ring.
Still not quite enough throw, its very close. I'm still tinkering with it.
Now I need to order another 40t for the timing chain.
