Help/options for replacing Trek 7.3FX BB

I have a Trek 7.3FX bike that I've had for a couple of years. I'm interested in improving the bike a bit and have been looking at options.

One thing I'd like to do is perhaps replace the bottom bracket. Trek have told me this is a 68x122.5 square taper.

One option would be to replace the BB with a lighter version of that installed. It has also been suggested that I switch to Octalink.

Problem I'm having is that I can't find any BB other than square taper for the size I need.

Anyone any ideas what I can do?
