Bose L1 Model II - Brass ensemble

Hi!

At the moment i am using a Bose L1 Compact, to mic up my sousaphone when my band gigs at smaller venues and outside.
I am in a band with 2 trumpets, 2 trombones, 1 sousaphone, 1 marching baritone, drumkit, and percussion.

Would the Bose L1 Model II deliver enough juice (volume vise), to give a little boost for the other brass instruments?
I am not talking about a full PA boost, but a little extra. I know the T1 Tone Match only has 4 channels, but if i take the two trumpets into one channel, the two trombones into one, sousaphone in one and marching baritone in one.

I am new here, but i hope you understood my question.
