Easy gathering of "Bushes"

Ok I need this for a rpg like map. The map is somewhat done and I think this model would help making the rest easier.
What I need is someone to just put together the "Dalaran Ruins - Bush" Doodads so they look something like the picture.
Variations would be appreciated.

Also a question, will this "model with 4 bushes" take lesser file-space then 4 bushes?

afaik by default every tree is as different model, and every animation of a tree is a different model, so better just make 1 bush imo

Well they dont have any animations,
but I atleast need the answer on the question.
Is 1 model with 4 bushes in it bigger then 4 models with 1 bush each?

trees haven't got animations? then i dunno what should i call when they are hit by a peon, or when they fall down...
but yes it cost less kilbites to make 4 bushes in 1 model, but u'd need triggers to show different ones not just randomly changing bushes

well these are bushes, not trees.

i misunderstood u, im sorry
edit: i can find only 1 bush type on dalaran ruins and 4 altogether(2felwood,1cityscape(dalaran),1ashenvale) so i dont see the point if u use default doodads (probably i misread the 1st post, so its better to make 4 ingame destructibles than 1 custom doodad with triggers).

i think he wants them as different variations, doesnt he?

No what I meant was geomerging 4 bushes to 1 model. And it would be nice with different variations and by that I mean that each bush would be placed in a different place and with an different angle.

so u want 1 model that looks exactly the same as in the screenie?

Well somthing like it, and as I said before, variations would be appreciated.
I could prolly do this myself If I atleast had some modelling knowledge and a Geomerge program.

ok, i hope that what u meant
Edit: oops i forgot about the pivot point so it won't rotate correctly
