I remember coming across a thread on LST a couple of years ago ... where this tie down method was used, but instead of training the main stem to go straight in a selected direction, it was trained to circle in an expanding spiral shape.
For those that train their plants already, you'll know the newer growth near the branch end, is a LOT more pliable, and actually not that difficult to coax into a circular shape ... so if you were doing this regularly, shaping the main stem into a spiral formation, parallel with the ground with multiple points onto a horizontal rebar screen at top-of-the-pot level is very doable.
You'd want it to be a fairly loose spiral, to give the side branches room to develop within the spiral itself, but the structure you could create could be REALLY interesting, and has the potential to create a plethora of 'tops'.
The skeleton, once harvested, would be funky!!
