I think the 10" lift is cool and all but I do not see a big market for it. Currently the market demands 35-37" tires. You can pretty much go anywhere you want with 37" tires. If your looking to make money then design a 5-6" lift which will clear 37" tires. Designing a lift to fit tires larger than 37's will cause logistical problems like the vehicle will be underpowered and gear ratios are limited. Also the components like the differentials, CV's and axle shafts are not capable of taking the abuse of tires larger than 37's and I think 37's are pushing it myself if people ever plan on using this kit offroad.
