I too have thought about this type of design, but the reality is that when I experimented with it the complications and weight savings diminished it's value. Your design has the pole straight up, which greatly reduces it's utility...I'd want to be able to sit up to change clothes, etc. Now you're dealing with offsetting the pole or using two poles to free up the room. I have been using a 10 oz similar shelter this year but it's only for sleeping (I wrote an article under "multiuse gear" earlier). Once you get into the 10 oz range and beyond then a cuben tent like a ZPacks starts to make more sense. I found that trying to stake out a slanted pole (to create interior room) became such a complicated hassle that I pitched that idea and ended up with using a flexible delrin rod instead to keep fabric off my face.
