Can anyone think of a reason why migrating some Shimano 600(older Ultegra) shift/brake levers wouldn't work on the bottom side of bullhorn-bars?
Working on a new bike, and I don't like drops for the city

Had that same setup with a 8 speed 105 tri bike. Worked fine.

So you had no problem reaching the break levers from the flatish bullhorns?

I dont see why the sti's wouldn't work, but if you want geared bullhorns, try bar-end shifters in the ends, with interuptor (cyclocross) levers clamped around the end.

You'll rund into a problem of running the shifter housing under the clamp of the brake levers, but Pyramid (J&B house brand) makes cyclocross levers in the larger diameter, and provides a shim. I filed down the shim to allow the shifter housing to pass through.

The barcons went from side to side, instead of up and down. I used (and love) suntour bar-ends. Some on ebay now: http://cgi.ebay.com/Suntour-Barcon-Shifters_W0QQitemZ7239998828QQcategoryZ27950QQrdZ1QQcmdZViewItem

With the above setup, you have braking and ****ing all in the same place, and rapid up and downshifts involve one motion (moving the lever) instead of several (clicking the STI several times).

I think that I forgot an "f", but I'll just leave it as it is, because the 13 year-old in me is laughing heartily :D

I'm trying to reuse as many of the current parts as possible, and I've got the STIs already

Two of my fellow riders in my Tuesday club ride use bullhorns with STI. One even has secondary brake levers on the tradtional tops.

Shifting and braking wasn't a problem. I ended up putting in conventional drop bars because I wasn't doing many TTs and wanted a regular road setup.
