Hi so in basic terms I have created a new framework for the followers ai 
so now you can recruit 20 followers on top of the other one.

:Installation

First you install my mod with a mod installation program like ( Nexus Mod Manager )

Then you type these commands into the console:

The first command for team 1 is

( setconsolescopequest followers1 )

Then select your npc you want in the console then type:

forcerefintoalias recruit01

setplayerteammate 1

sifh 1

and for the second one you do the same thing but type

( forcerefintoalias recruit02 ) 

instead of recruit01 you type recruit02

Then next command for team 2 is

( setconsolescopequest followers2 )

and the the same as before but instead of recruit01 and 02

you type this:

( forcerefintoalias recruit03 )

and 

( forcerefintoalias recruit04 )

the next team is

( followers3 )

and then

( recruit05 )

and
( recruit06 )

the next team is

( followers4 )

and
( recruit07 )

and

( recruit08 )


the next team is

( followers5 )

and
( recruit09 )

and

( recruit10 )


the next team is

( followers6 )

and
( recruit11 )

and

( recruit12 )


the next team is

( followers7 )

and
( recruit13 )

and

( recruit14 )


the next team is

( followers8 )

and
( recruit15 )

and

( recruit16 )


the next team is

( followers9 )

and
( recruit17 )

and

( recruit18 )


the next team is

( followers10 )

and
( recruit19 )

and

( recruit20 )

Just use each followers quest with "setconsolescopequest" 
and then force the npc in your console screen into a follower slot "recruit01, recruit02, 09 " etc

This is my mod i would prefer people ask before including it in any of their work.
Have Fun!
