Bruce, I'm curious, why is the tuba part is better covered by Baritone/Euph?
My copy (from when Robert King was independent) had Euph and Tuba parts and the Euph covered all the tuba stuff (an octave up sometimes) but had more.
Back to the original topic: I like the Renwick Dance, but it's shorter than your target (but a big challenge!).
You can try the Suite from the Montragian Hills (it's much harder to read than to play).
There are a couple of Bach Prelude and Fugues that would probably meet the time requirement. The G Minor is used in a lot of horror films.
You could consider a suite of Pezel pieces. There are 55 of them and each is about a minute long. I have a score that is for 2 soprano trombones, alto trombone, tenor trombone, and bass trombone (all written in C) but there are a few of them on IMSLP arranged for conventional brass quintet.
Want an ego trip? Get the Canadian Brass arrangement of "Just a Closer Walk with Thee". (Warning: improvisational section in the key of D for you and E for your 1st Trumpet.)
One that every quintet I've ever played liked a lot (but may be just too long) is Tribute to MGM. Sometimes we cut sections out because of time constraints so you might be able to cut it back to meet your time limit.
