Hoping you guys can help me

I'm thinking about forming a jamming group with me on bass, a keyboard player, reeds [sax or clarinet], and drums if we can find. I'm thinking about just jamming for fun, then move on to other stuff if we feel like it [on a college campus btw]

should i get a brass player? [trumpet or trombone]
play covers mostly?

suggestions and anything else welcome

I play in a band with myself on trumpet, a tenor sax player, keys and drums and we do a lot of Weather Report and it sounds great. Not so much Headhunters, except maybe Chameleon every once in awhile (>.>.
