This ripping out outlanes business is for PAPA A only. Two things causing this relevant. Top top players, and a system allowing reattempts. Otherwise I do not see the point.
The trick of setting up games is to find the optimal luck/skill balance in regards to the player base. A fair playing (and 100% working) game. That still cannot be abused by the best players. And this because of game duration more than anything else, really.
A bastardised game, may be too much luck of the draw for intermediately skilled players. That might not find it their money and time worth. Short/unfair games and no fun.
I am not sure I understand your "harder" question. But outlane post adjustment is actually not always that easy. Being hidden under plastics and stuff. Easy to do things are: clean and polish the playfield, install new balls, calibrate the tilt (not too tight though and have room for warnings), fresh flipper rubber ring, fine tune the pitch. Easy to come by stuff that will get you a long way towards a fast and tough controllable game.
