I say go with the piccolo trumpet
They get the solos.
And you can effortlessly hit high notes that you can't on the trumpet.

Piccolo trumpet is not easy to play. It takes a lot of trial an error to find the right combination of mouthpiece and horn type (there are different bore sizes on pic trumpets that can really change how they are played).
Bass clarinet will give you more bang for your buck as far as an instrument that you can gain some mastery on without a ton of time.
If you are really looking for a fun instrument that hasn't been in the limelight for a while, try the flugelhorn.
