I was in this position myself and over the last 6years with the band I have gone from using no effects at all, to eventually using a full Diago Tourman crammed and now I'm down to 7/8 which I just about fit on a PT-jnr. All my crazy synth/filter/fuzzy madness stuff has gone, because despite wanting to create weird/incredible soundscapes for so long I eventually realised that it was better for all of us to just play to what the music requires. You can still use a variety of pedals, but as soon as it becomes obtrusive it will ruin the sound of the song. I mean different songs have different sounds, right?
So you could bring your pedal induced [s]madness[/s] creativity to the band and write something off the back of that, but as far as bringing total originality to already written material goes, you're walking a fine line.
