Welcome to Librarium Online!
I don't really know where to put this because the army will be half Witch Hunters and the Other Daemonhunters. Can you suggest what my base army should be and what to take.
Well, the real limitation for allies comes down to the number of units you can use. You're limited to 0-1 HQ, 0-1 Elite, 0-2 Troop, 0-1 Fast Attack, and 0 Heavy Support choices from the allied contingent, while the base army gets the standard FOC list (1-2 HQ, 0-3 Elite, 2-6 Troops, 0-3 Fast Attack, 0-3 Heavy Support). I would make the decision based upon what units you'd like to use, and how many of them. DH and WH have very different Heavy Support choices, for example, and you can't use ANY Heavy Support choices from the allied contingent. Also, the allied contingent does NOT need the usual 1 HQ & 2 Troops minimums, while the base army DOES.
My own choice would be DH with allied WH because I like to use a lot of GK units (2 Fast Attack GK units, usually) and I don't mind using IST for my mandatory Troops choices. I'd use a GK Grand Master & retinue as the HQ, no Elites, a pair of mechanized IST units, a pair of mechanized SoB units, a unit of Seraphim, those 2 units of Fast Attack GK, and ~2 GK Dreadnoughts for Heavy Support.
Alternately, you could go with WH with allied DH, and use just a few GK units to supplement the Sisters' good shooting - build a WH or SoB army, and ally in 1 Fast Attack GK unit. If you have the points, add in a GK Hero & GK Terminator retinue for an HQ slot, and if you really want to go overboard, a second GK Terminator unit as Elites.
We can probably give more specific advice if you tell us what units from each list you really want to use and the general list style you're going for!
definately whitch hunters as base we have by far the superier elites fast attack and heavy support i would suggest using a grandmaster with bodyguard and elite dh =][= and then 2 units of gk with the rest being wh (don't forget a wh =][=)

I'm inclined to agree w/ Meglomaniac, he is a veteran of these areas, and knowns his stuff well. He also gives very sound advice.
However, losing out on the Exorcist could be a bummer, but it means you can get a LRC.
It's all bout what you wanna do, do you need the extra slots for a specific army, or you got like one slot of each (cept for troops) you wanna fill out.
I usually switch between WH+DH and the other way around.
But it really depends onwhat you wanna do like Meg said.
