I see.
Hm.
Not looking to be a killjoy/smarta** or whatever here, but from a pure technical point of view, in retrospect wouldn't it have made more sense to start with the stilt system and build the rest around it?
Unless you already have build up some experience with such systems, getting it right can be a pain in the .... you know even with just the load of a human.
I know because I've once tried to help somebody with a stilt system of 50cm -not cosplay related-, so roughly 1.5 foot high several years ago.
It was a very bumpy road and in the end we needed a lot of help from people with auto-mechanics backgrounds to make it halfway safe.
Long story short : it worked, but the end result in terms of dimensions, even the way it worked were totally different from what we had in mind in the early stages.
As the stilts will be essentially the foundation of the whole armor, my gut feeling would be it's easier to adapt the suit to the stilts than vice versa.
I also seem to remember having seen a similar idea somewhere in an Elite build, and the stilts as a project took a complete life of their own there too if I'm not mistaken.
(not looking to pull the legs from beneath your chai... euh ... Hunter, like everybody I'm sure I'm totally rooting for you as when this is done, it will be nothing short of spectacular).
