Actually you could go a step farther. Disable all 4 engine bombers. Disable ord, so that light bombers could still fly. (A20, b25h, etc)
I think it would make a nice choice along with our current main.
If enough people flew there they might even be able to drop the main arena caps.
From what I've heard over the years I don't think it takes that much in the way of system resources to host an arena. So I see no reason this couldn't be done.
More choices = more bang for the buck = more happy AH customers.
