Seems unlikely to work given (if I understood correctly) the main direct consumer is Babel, another OSS project that is known to have had trouble with funding in the past. If he starts asking for license fees, Babel eill just be forced to make do with the latest OSS version, fork it or whatever, and the rest of the world will never know.
