Well if you can get a new skin for the kite to show your guilds emblem how about a upgrade for the string and handle.
The string upgrade would be a longer line that could get as high as some of the buildings in LA and add a number 1 skill Let Out/Climb and a Number 2 skill Retract/Dive. And the handle upgrade would add two new skills Number 3 Glide Left, Number 4 Glide Right.
And a small tail could be added to add more skill(s) to do tricks like 360 or loop da loop, the axle and maybe the yo yo.
