I'm looking at that option too my problem is the rear will need to go out by around 30mm each side, which is very expensive. Then ill need to buy longer studs. I'm running 5x100 which seems a little more costly than 4x100 too. I'm getting the new rims tomorrow hopefully, they are 5x100 but the centre bore isn't 57.1mm, it's slightly smaller so need to get this addressed too.
