IMO you would also have to accept that this design does not allow for sufficient locks to allow the legs to retract into themselves and, on the face of it, the legs themselves would need guiding in and out to rigid positions, being tapered.
You may just be 'locked-in' to whatever height you started out with. Your locks would also need to be flexible enough to deal with the various leg dimensions.
By the time you have your legs at a real world working dimension (out of affordable materials) with locks and center post to legs/hinges mechanism you might as well bought an existing tripod, like a Gitzo, or learned the ins and outs of monopod photography.
This is not to say it can't be done, but unless you have the ability to, or the deep pockets for someone else to make your vision with state-of-the-art carbon fiber, alloys or what have you, you may as well rejoin the herd and 'settle' for the norm.
Anyway, that’s the view from where I’m standing.
