Adding more battle map textures

I was wondering if a CA member, or anyone really, could answer this for me.

I have made a new texture set, a Mordor texture set, and placed it all in a folder named Mordor with all the other texture folders, I have simply compied Temperate and edited them so the number of plates is around 180. Now what I need to no is, is there a way to allow me to use these textures in the current Mordor folder, or do I have to wipe over the files in another folder to make them work?

ORIGINALLY developement plans for medieval called for alternate terrain sets to be allowable,
but somehow the core code writers never got the idea...

so while you "can" identify alternate terrain folders in the map definition file, alternate terrain options will not appear when you select a custom battle to play, and thus the alternate terrain will not be used for a custom battle

>> which brings me to a thought

I just had a thought, look at this.

Terrains:: LUSH ARID ROCK_DES TEMPERATE MORDOR

Architecture:: LUSH W_EURO
Architecture:: ARID S_EURO
Architecture:: ROCK_DES ISLAMIC
Architecture:: SAND_DES ISLAMIC
Architecture:: TEMPERATE E_EURO

Game_Types:: SP_BATTLE CUSTOM MP_LAN MP_INET

MP_Styles:: LMS KOTH CTF

(I will add MORDOR architecture before I test it)

Do you reckon I could create a map using a different texture set and then simply edit that part of the file to change it to MORDOR exclusively by deleting all the other texture sets?

EDIT-I tried as you suggested but it simply removed Agincourt as an option.
