No. I have problems with items 1, 3, and 4 of the proposal. The main problem I have is with item 4, which states that the nekos will be phased out of jobs that would be better suited to the Yamatains. It was my understanding that the superior qualities of the nekos would make them better suited at any job, than a human. That was, I thought, why the nekos were created, was because they would be less vulnerable to on the job risks (Disease or death), than humans. The other issues are, for item 1, who will be altering the nekos from now on? The nekos themselves? You say there will be no other entity allowed to modify the nekos, so I am guessing this genetic department would be run by the nekos, for the nekos? Item 3 says that free upgrades will be given "From any other species, to the Yamatain", how are you going to enforce this? What if one species doesn't want to give an upgrade to the Yamatain, are you going to attack their planet and force them to?
There are too many vague spots that were not addressed. I would think about changing my vote, once these questions and vague areas are addressed, but for now, I vote no.
