I agree with your assessment that donations do not work. Now let me solve your problem: Instead of running into the tragedy of the commons by asking your userbase collectively to donate 1k, you can announce that you will start working on v2 now and let users pay to prioritize individual feature requests in each new release. Start with a small release adding only a feature that you want but nobody else requested to prove that the project is active again. Create scarcity by only doing 1 release / timeframe and only include the feature with the most money pledged. Hope for a bidding war.
