We can add a drop in bolster between the two bolsters of the current 28 Active Thunder.
Alternatively, we are currently tooling a new 29 Active Thunder which will be scale build of the 37AT of 6.5:10. (Roughly a 2/3s the size of the 37.) They will have very similar looks.
The new cockpit will have center or side cabin in entry options, and 3 bolsters across the front will be available with either option.
