Hey, i really like Daemons (Tzeentch and Nurgle most, but the other two are also okay) and Daemonprinces are my favorite Models (have 8 of them + Belakor

)
So i wanted to know if a 2000 Points matched play army, with 3-4 Princes can be good?
I wanted to make a mixed Tzeentch and Nurgle Theme, but i don't have any clues how to make a decent list with them.
My 1000 Point List often look like this:
Leaders
Be'Lakor, Chaos Daemon Prince (240)
Lord Of Change (260)
- General
- Trait: Great Destroyer
- Artefact: Crown of Conquest
Units
Plaguebearers Of Nurgle x 10 (100)
Plaguebearers Of Nurgle x 10 (100)
Flamers Of Tzeentch x 3 (200) (Summon Pool)
Chaos Warhounds x 10 (80)
Total: (780) 980/1000
Not that good, but i like it somehow.
So how can i build a decent list with enough punch and durability and with two other Princes?
Should i reserve most of my points and try to summon spam greater Daemons?
Maybe a mixed list with mortals can do some work?
Does anybody have such an army or something in this direction?
Looking forward for some answers^^.
