Would you be willing to endorse this proposal? If not, why not?

This particular proposal? No.

But mainly because we already have the tech to effectively cure malaria; it's called "DDT" and the only reason we aren't using it now is a lack of political will to challenge the environmental movement. If we lived in the Donaldverse where this proposal could be taken seriously, it wouldn't be hard to get a widespread mosquito eradication movement started; after all, sentimental concerns are the main reason we're handicapping ourselves here in the first place.

In general though, I think human experimentation does have merits. So much of what we know about our biology, especially the biology of the brain, comes from examining the victims of rare mutations diseases or accidents which impaired the functioning of a specific chemical pathway or tissue. If we could do organized knockout studies there is a good chance that we could gain a lot of knowledge which otherwise might take decades to uncover. But like a lot of other interesting ideas, the Nazis kind of messed this one up for the rest of us; there's really no chance of this sort of thing being allowed in the current political climate, so speculating about it is idle almost by definition.
