So, as far as i know, the mode switching thing is gone. Sort of. This is going to be a pain for people who didn't rank up to Admiral/Duke like me 
What i'm suggesting is this.
In superpower capital systems, that is Sol, Achenar and Alioth, there should be additional option under "contacts" - auxilary navy contact. There, you can ask for special missions for rank progression. They won't give you money, but will give you more rank progression than usual missions. They need to be really difficult missions. Example, feds: "There's a war in Perkele system. Empire brought Majestic interdictor into a conflict and is curbstomping local factions we would rather like to succeed. Your goal will be to drive it away 5 times, giving our friends a little breathing room. But obviously, you're not a federal pilot and if you're caught, we'll deny any knowledge". Or hell, maybe even ask people to get some loca faction to x influence % by any means necessary, getting people into BGS - at higher ranks, of course. You can think of anything interesting.
Yeah, it's simple and somewhat boring, but beats waiting for 15 minutes before you can grab another load of donation missions.
