First of all, I say this discussion is most welcome in this forum.
I say the guying has some things in common with KiteX windmill
You could maybe try to figure out if the tower height is limited by not having guying or maybe there are other reasons why current windmills are not higher. Then also do a comparative cost analysis of your design vs current trends. Then do a mass analysis. Simple steps to increase your understanding of the problem.
I don’t want to take away your motivation. But from me the gut feeling is thumbs down. But you should make up your own opinion. I havent done near enough analysis to have a good opinion.
