Changing Game Values on private LAN

A mate of mine is coming over for a game of Generals Zero Hour
tomorrow. I would like to know if its possible to setup a customised
game on my home network and set it up so that my vehicles and troops
have 20% less armour, or that my mate starts with twice as much money
as me. This is because we're both at different levels of play, and
it'd be pointless playing it on equal terms.

If not, then we'll both play on the same team against a team of two AI
players set to the HARDEST level and a MEDIUM AI player.

TIA,

Colin
