I can almost guarantee that your payment of 15x the normal amount would still be too little versus how many versions will be compiled and distributed for free with premium features enabled.
That depends on how many people feel the same as me, and I know how we could find out.
While it seems to have fallen out of favor, crowdfunding is excellent at helping to resolving that kind of uncertainty.
@ljdawson, please consider how much it would be worth to you, and start a campaign. Go open-source If the target is reached.
