On continued review of this, I don't think design tweaks are the answer. The prototype fails on two counts really; 1) it looks bad and 2) it doesn't really provide a lot more protection where it's needed most... namely the face. I think maybe what's called for is more of a lightweight helmet with face mask. Just a few years back, rodeo bull riders were still wearing cowboy hats. This was pure tradition and looked good in context of the sport. Now, every bull rider wears a full helmet -- not a helmet designed to look something like a cowboy hat, just an actual functional helmet. The reality of needing this protection simply outweighed the tradition and normalcy of the cowboy hat. After seeing the baseball prototype in action, I'm thinking the same thing will probably have to occur in baseball. What's really needed is a helmet/mask designed specifically for use by pitchers... with proper weight, balance, protection, functionality and appearance all factored in. Then guys can opt for it or not. If there's initial stigma, at least there would also be fuller protection as a trade off. Who knows, maybe that's the intended end game with these oversized lid prototypes.
A straight up batting helmet or third base coach's helmet would look no more conspicuous than this prototype.
