Here's the problem with this suggestion, right now LW's uses the native SA checkpoints to enter buildings, eat food in fast food, buy ammu-nation weapons, gamble, all that. Unless the NAM entrance was blocked with some sort of object on the outside and there was a cp that teleported you into this new interior, then it would mean that there would have to be some work put into making all the custom cp entrances for all the interiors we use on LW's, also the shit like ammunition guy, fast food workers, casino dealers, would all be removed. That would be cool, that all that is removed and replaced for something scripted and server sided, but it would mean a lot of work and I don't know if the scripting team is willing to put that on their long long list.
