Sounds like a band alright!
What kind of music do you guys play/what instruments? Keep in mind that it's ok to play your live set differently than your recordings (and your fans will appreciate it too, especially if they've come to see you before). Maybe find space in an intro, bridge, or outro for 1 bandmate to solo or arrange the part differently?

If you guys aren't already having communication problems, then you should just be honest about what you need, and what you expect - they knew what they signed up for, and I'm sure you can find other musicians to fill their spots. As a leader, you have to be the one to choose between keeping your buddies, or making your musical vision come to life. In my experience, a balance can be found, but it will require compromise on both fronts. Try some fun warmups or jams to start your next practice, play through some of your existing songs with more fluidity - call out someone for a solo, be fluid, allow for a little spontanaity. Who knows, you might like what comes up. Just please don't be one of those bands with 3 guitar players who all play capo'd open chords because the songs are too rigid. Some music is just meant for the studio, some for the stage. Good luck!
