Wouldn't this already be effective as long as the project was under the umbrella of an appropriate 501(c)3? Not necessarily the repatriation bit. I'm not a tax expert by any means so I am legitimately asking.

From a quick search, it looks like the IRS does sometimes allow businesses to make deductible contributions to a 501(c)3, but that it first attempts to determine if the business expects to receive a "substantial return benefit". [0]

The IRS seems to already have specific rules around "qualified sponsorship payments". [1]
