Gick Speed may have a casing if you need one.
I did contact him and he has multiple cases available for replacement. I didn't ask about repair, though so I should probably check on that.
I've also seen some nice welding of aluminum from Gick, might give him a call also. He has experience with these cases and scooters.
I have a set of smallie cases. pm me.
Big thanks for everyone's help here. It looks like I'm not in nearly as much of a bind as I was afraid I was. It looks like there are a few good options to choose from.
