3rd Row Seats on Shogun - weather

We have a seven seat Mitsubishi Shogun which has given 5 years/80,000 miles of fault free motoring to our family of seven. Whilst the space between the 2nd and 3rd row is adequate, the lack of height from the floor makes them uncomfortable for my children as they grow. They do however, have plenty of head room to spare and it appears geometrically possible to modify the seats to give them more height. Is there anybody who offers a modification to raise the height of the 3rd row seats in LWB 4X4s?

Raise the height of the child instead of the seat by putting a booster cushion under your offspring. Much cheaper.
