Im a US dude.  Long time gymnast. Mostly bought a pair of jump stilts  to bounce around town to promote my businesss.  (Trampoline and Acrobatic school). Not sure if I'll make the papers as an article of a local crazy man or a police blotter about hauling me off to the hospital:D

Just throwing this idea out there for ya'll to ponder.

Long ago a dude invented the Bab System for teaching gymnastic skills.  Basically its bungee jumping with a bungee on each side of you. 

 

Pic a tree and a tree, Tree and balcony, etc etc.  Get some surgical tubeing.  Tie them off so that the tension would prevent your head form hitting the ground even if you dove to a handstand.  Willl take several tubes in a bundle most likely.  Right tension Im guessing would be about the same as it holding you just off the ground W/OUT stilts on. But that is just a guess!!!!. 

Build you a belt.  Mountain climbing harness? safety construction worker harness?  order a gymnastic spotting belt?

Then put on your slits.  Lean against tree/building etc.  You might have to put a rope onto the belt to tug it down. secure rope with a clip to belt but tie off the end to something low out of the way.  Put on belt.  Relase tug down rope from belt and pitch it off to the side.

JUMP AWAY.  Test out the safety range of the bungee cord.

Do a lot of experementing of the range of motion of things before you start going full tilt.

. Wear a helmet AT LEAST. 
. USE AT YOUR OWN RISK!!! 
. Assume Im full of SHIAT and trust nothing I say
. Fully test it out (put your buddy in it first :p) etc.
. You assume all risk

Good luck

watched your vid pretty closely.  Good job.  My Masters  study is in Motor Learning (Biomechanics with some other stuff thrown in) and after watching you and others jump I can say for more input on this go watch some champion trampoline vids.  Slow them down however you want.  The technique is pretty much the same.  Also watch a little Double Mini trampoline. The take off onto the first part of these type of tramps is the same take off for the run hurdle punch approach you demonstrated here.

Hope my cheapo Craigslist stilts get here soon.  Imma going to kill myself trying to use em (I'm 46yrs) but Im hoping in the process Ill attract some crowds and excitment around town to get PR for the trampoline / Acrobatics and Dance school I own
