The 2008-9 bullitt is nice but it's really only cosmetic when compared to the upgrades over a standard GT in the 2001 version. I really enjoyed my 2001 Bullitt and would like another one someday, I would not have traded it in on anything other than my Stage 3.
It just seems to me that the new Bullitt is missing something.
Like others have said, why not build up a GT to what you are looking for performance and style wise. Or even sit tight a bit and see what the 2010 has to offer.
Based on your sig, I really don't see a problem with your current ride though.
