If you reduce the oil to a reasonable amount, you are putting the vitamin E deficiency back. If you don't come anywhere close to approaching 100% RDI of half of the known essential nutrients, then you are proposing a poor alternative to something that covers 100% of all of them. Especially when you require 20% more calories to still be massively deficient. The fact that an all twinky diet would be worse does not make your option a "potentially healthier" alternative to soylent.
