The first possibility, and likely the much more competitive one, is a Khornkin force themed around the Knights of Blood successor Chapter.
The army would feature an unhealthy amount of Flamers, ('kill, maim, Burn it Super Dead!!'), a Gorepack + Boodcrushers led by a Jugger lord to re-inforce the knightly imagry/theme and some MSU Bloodletter/Cultists to help generate Tithe points.
Plus the added ability to simply boil every tactical decision down to "Khorne Wills It!" in true Kingdom of Heaven fashion!

It would be the complete opposite gaming wise as well to my current Tzeentch Daemons, as the force would have 0 psychics and is focused almost entirely on assaults rather than shooting + magic.

Their colour scheme would be this: http://vignette2.wikia.nocookie.net/warhammer40k/images/d/dc/KnightsofBlood2.jpg/revision/latest?cb=20120730083852



The other idea I'm toying with is an army of the renegade Magma Hounds. Lots and Lots of Daemon Engines + Hellbrute formation. Oblits, a solo Mutilator or two and MSU Marines toting high tech gear in the form of Plasma weaponry, plus the obligatory unit of Chosen with an unhealthy amount of Flamers.
All led by Warpsmiths & Sorcerers who create the vast array of daemonic monstrosities.

On the plus side, it would synergise better with the existing Daemons, as they can augment most everything with masses of Malefic + Divination. I would even consider (hereticially of course) of using Plaguemarines/MoN to represent the marines being heavily augmented with bionics and/or being part daemon-forged themselves.
On the downside, it would make heavy use of some of the worst units in the codex, but then, my dice don't allow me to win games anyways, so stomping opponents isn't a deciding factor!

Modeling wise, I'd be mixing in a number of Space Wolves bits - especially the wolfhelm head!
Their colour scheme would be based around these guys: http://vignette1.wikia.nocookie.net/warhammer40k/images/d/d7/Hakanor'sReavers2.jpg/revision/latest?cb=20120730083427
