I see what you are saying and frankly it would make sense although I guess it would mean more programming for WGT.
The ability to put overspin and backspin on your drivers does what you are suggesting to a degree. I play the R11 and putting backspin on it makes the ball fly higher with very little loss of distance I might add, even into the wind. The overspin delofts it a little as well and helps some into the wind.
You are probably going to have to just use what the WGT has available since I doubt they will make the multiple loft drivers of the same brand.
