Can someone mod a pause feature that doesn't send you to menu?

[Datheus]

Want I'm thinking... could someone make a mod where you can pause the game in SP WITHOUT going to the menu? What I have in mind is somewhat like when you pause an MP game when you're only playing bots, just without that menu...

 

I'm thinking that it should be pretty easy... either somehow make the cl_paused cvar not read only... or possible change the menu file name so that when the game goes to open the file when you press the ESC, it can't find the menu, thusly not loading it

 

Any help would appreciated
