So first attempt: get a 26T front chainring with Campagnolo/Shimano offset, and get a longer b-screw, and try that set-up.
If no luck there, will convert whole crankset to Sugino XD 600.
Will report back in a few days.
Thanks, all!
I would not bother getting a different chainring, instead get the chain catcher to keep the chain from dropping off the chain ring. I just did a google search for chain catcher image, here are a couple good photos of what I am talking about.

If you do switch to a Sugino crank, you are likely getting a different bottom bracket as well. Campy square taper (if that is what you have) is ISO, the Japanese use JIS square taper. Some people have mixed these tapers, but I prefer to stick to the correct square peg in the correctly sized square hole.
