Well, since you are so standoffish I guess I feel compelled to reply.
Judging by the pic, it's hard to tell if there is sufficient room between the pan and wheel so I just thought I'd ask if it was possible or there are plans to guard that area. Since this is a project, others may want to emulate and one may not consider that small fingers may get wedged between the pan and tire. Obviously since you and your child are impervious to injury, this doesn't concern you but others may want to be made aware of such possibilities.
