Although the stuff I have on here (I will very soon take everything off as to not damage my reputation (HA! :D)) is not very good, I would like to be a part of this project. I have not had time to compose properly because of pianistic commitments. However, I would still like to compose, if only little piano pieces (which is what you're offering!). If pieces were too difficult, then ossias could be included - this would include, perhaps the differences in a piece needed in order to suit an adult, or child beginner-learner (adults could manage greater stretches, of course).
P.S - also simple piano duets, or teacher-student piano duets could be composed - I'm getting excited...
