Not always the easiest way is the best way. Rs3 became a pay2win game, look what happened. I don't think that the majority of the players would want to have winged, purple skin coloured dudes running around with all kinds of funky ass items and benefits that are totally unlike what Pali has been going for so far - a server as close as possible to the original osrs.
I'm not saying that it would fail in terms of earning more money = gaining more players, but it would make the game pretty disgusting in my eyes.
