Idea to bring back the silent assasin mod from payday 2

Description of the mod from payday 2:

"This mod changes Payday 2's stealth gameplay changing the dynamic created by guards and pagers. Now, when you kill an unaware guard with a single shot, no pager goes off. The guard died too quickly to call in reinforcements. To balance this new power, the number of pagers has been reduced to two from four.

In addition, this mod adds a new dimension to answering pagers. Operators are no longer fooled by hearing the same voice over and over again. Along with limiting the overall number of pagers, you may limit the number of pagers each player may answer. For example, you can set the total number of pagers to 2 and the number per player to 1. So you can answer two pagers total, but if the operator hears the same voice twice, it's bulldozers and shields time."
