Uh, couple of things I thought to say about Kiyoshi's sheet. You... contradict yourself a few times there, you know?
First of all, Sakura's original eye color was blue/aquamarine, like Rin's. Not Green.
Second, you call Kiyoshi an "average magus", but he clearly is not. Not only does he have two elemental affinities, one of which is very rare, you describe him as having the potential to excel at Reinforcement, and he can already self-reinforce at his age. I'm not sure you realize how much of a big deal self-reinforcement actually is, but it's the peak of basic magecraft. Rin can do it because she is a goddamn genius!
Also, allow me to clear one further thing up. Shirou does not "excel at Reinforcement". The only thing he is good at is Projection, and that is because of UBW and his circuits being tailored specifically for it. He is also good at Alteration and Reinforcement on weapons because of his affinity.
Sure, he might be able to do Reinforcement somewhat well, but he by no means EXCELS at it compared to someone like Rin. Or he's not supposed to, anyways. EMIYA is a different case. It's possible Shirou is able to self-reinforce efficiently and quite well if he does something like think of himself as a sword or do it subconsciously (this in particular actually seems to happen in FSN a few times, but it's again in relation to the first point, or so I speculate).
But he does not excel at Reinforcement in normal terms.
POST-EDIT: I only now realized everyone else already mentioned these points, but I'm posting this anyways because I already spent the time writing it to explain.
