Hey Dave, welcome to the forum. You have options but most of them will cause fairing clearance issues.
Look at where the grips are when the steering is at full lock. Not much room to go up Try a Lightning XBS!
1) You can get ebay clip-ons that clamp to the fork tubes and have risers, but you'll need to cut off the mounts on your upper triple for clearance

2) You can get the upper triple from a lightning and get whatever bars you want (check tube diameter, IIRC your '03 is special). You'll have to do something with your key as well.
Listed wrong, but what you need. https://www.ebay.com/itm/Buell-XB9S-...DW9n:rk:1:pf:0
3) Replacement clip-on tubes with a "Z" (Ebay) but IMO I don't trust them.

The links are just examples of what I'm talking about, but really you should go get a Lightning and make sure to test ride it first!
