Question about editing melee map

[Ravager16829]

Is it possible to do these things?
1.Change the starting Town Hall to T3 ones (Castle, Fortress, Black Citadel, Tree of Eternity).
2.Make computer only train certain heroes (like the Humans with Archmage, MK, and Paladin, but no Blood Mage).
3.Make computer heroes train neutral heroes in melee game and learn spells (without AMAI, but just a simple trigger).

I want that because I'm trying to do some fun in melee games. I'm using the 1.29 client downloaded from Hive Download Archive (not the Legacy version that's shipped in Battle.net app).

You should be able to.

2.Make computer only train certain heroes (like the Humans with Archmage, MK, and Paladin, but no Blood Mage).

Yes.

3.Make computer heroes train neutral heroes in melee game and learn spells (without AMAI, but just a simple trigger).

IIRC, you should be able to, but its tedious.
