I think they'll need a bigger team working on the game. Without major fixes, they are already releasing content at a very slow rate. If they really added the polish to the game by fixing, updating engines, we probably won't see anything new for a year, lol. And a lot of players in game (those who don't use POF) will not be very happy.
On another online game I play, they had almost 100 people working on the game. So if any major fixes needed to happen, no problem! They can easily do both at the same time.
I doubt POTCO even hae 50 people working on the game.
Edit : According to Team Bois :

There are only 19 people working on the game.
