I thought of this a while ago. Might try it in a few grows. I mean, if ya look at it, it does seem like a really great idea. When you analyze it though, the buds up top are going to get so big, they will block the light from the lower buds, essentially rendering this as effective as an untrimmed SCROG. No doubt it could be built upon and further refined though. For example, create a slanted cage like this / and tie the plant up to that. It won't save vertical space, but it will allow the light to hit each and every bud site, and there will be no chopping required to the plant... although advanced grow techniques would likely increase yield.
