I don't think Mr. House would be too fond of that idea...
Well if you think about it.
If they made this a DLC, and you work for Mr. House.
Mr. House side: When you aproach Mr. Houses computer terminal, he will ask you somthing about his casino. "You see the 38, after the bombs fell, people ransacked there way into the building, trying to get safe from the outside world. My robots were not programed to fix the place up. If you would not mind, i would like to see my casino opened again. I know of places you can get new slots at, then you could hire some people to work the tables. Also, i need you to try to clean the place up, im sure your friends wouldnt mine a little clean up job" Then you fix the place up and it opens for buisness. You could then get a weekly payment of 1000 caps, or somthing.
Wild Card: After you set Yes Man in control, he suggest that you re-open the lucky 38, he suggest that if its open you could earn extra caps, and make every one happy!
NCR side: After the NCR send you to kill Mr. House, they ask you to kill all the robots on the strip. After you clean the strip of these robots, then NCR moves in forces and begins annexing the strip. Thier first step, take over the lucky 38, open it, and use Mr. House penthouse as a base of operations. They give you a weekly pay of the casino seeing as you helped them annex the strip.
Ceaser Side: This DLC would open up alot more side quest for Ceasers Legion. Most would be on conquering towns. But one of them, the main objective for ceaser, is to take over the strip, and kill any who apose. It starts with you and a group of ceaser marching through Free side. NCR soliders move in on you and start shooting at you. As you fight your way to the strip people hide and NCR rush you from all sides. When you reach the gate, a squad member radio's in that you got to the strip. Then another squad responds saying they breached MCarren Airport. At this time you are to take over the strip.
