Not trying to step on rockets toes with this one, but scaling a resin cast order for such an item just doesn't work - too many molds to make several sizes of all parts. If there were like 200 people buying this, maybe different sizes would be offered. But for barely a dozen, this will be a one-size-fits-all. I think k the better question is: is there room to overlap the parts to fit a variety of sizes? I would think k the kit would allow at least a couple inches of sizing difference. Will await curtis' final answer on the slight adjustment, but for such a select few 8nterested, I would plan on making the screen size work
