You have the right idea my friend , this will make a interesting mod .
Heres some C&C for you
the idea of hopping to each platform so cool and all but its missing some mod magic. try adding some enviromental objects for looks , mabey a few chains to swing just incase you fall ( the you can swing around the side and save your self).
Personaly i would change the colors of the pedistles to resemble light and dark wood for a outdoors feel.
Remeber , experimenting with object joints can give you awsome resaults .
Keep it up bud !
