Howdy stepdad...I am not a expert..still kind of a noob..I have about 6 grows under my belt..a few autos and a few photos..with pretty good success..lol of course i have killed many more than I have grown out in the learning process.
I have used lst on all my grows for space reasons and I do it just like you seem to be, and it has always given me the control i needed and my yields have been what i expected pretty much every time. I also have started putting my seeds near the edge just like your drawing shows, for just that reason.and some I have tied across, and some along the rim to "curve" her around the pots edge, and depending on the strain, again i have had success, but i will note that the strain does make each plant respond differently to lst like that. some that are a more bushy strain, will give the multiple bud sites when tied down, and some that tend to have a main cola sort of curve around the edge in a different manner due to the lack of many side branches. but all have seemingly responded well.
all that said rock on... your setup.. and ladies look good..good luck!
