I think you mean "Head Tube".
Have you looked at different stems? Something like a high angle (135°) Salsa will get those bars up even higher.
2 1/2" of spacers isn't much to get jazzed about though. If you think it looks dorky, you can always bling it out with some custom spacers.
I'd go with the faux diamond look

An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.
