As for the shorter stem? Yes that will work but it will affect the balance of the bike by opushing your CG back a little and shortening the stem affects handling. Neither of these are severe but they accumulate with the other things.
I will say I have a bias against bikes with shorter than 10cm stems.
You're likely right about the tt being too long. Alternatively it's possible the OP had his seat too far back to start with, the bars too low, and is really inflexible
The shorter stem will affect the balance and handling, true, but the effect (while riding on the hoods and in the drops) will be returning the balance and and handling to what they used to be with the old bars. I.e. weight distribution over the bike, and distance from the steerer axis to the front of the bars will be just what the OP used to have with his/her old bars. Riding on the tops of course is a different story, handling will be affected by the shorter stem.
