Okay, I'm a big SLIC fan, though I don't know an iota of SLIC programming.
But, if it's not possible to make the AIs like each other (c'mon, every AI is at war with every other AI all the time. How worse could the diplomacy programming have been?), by tweaking game constants, then how about using a simple SLIC program.
If you want to completely avoid having the AIs fight with each other (as an extreme solution, say), you can put in a simple line in the diplomacy.slc to the effect,
Begin AI turn{
"Every few turns, give 100 gold to every other AI"
}
I suppose this should make all the AIs go out partying together in no time!! Also, note the slyness of this piece of evil code - the AIs are not actually losing any gold in the balance!
The trickier part would be to write code that has each AI pick an (one and only one) HOTENEMY which it won't give gold to, without creating a snowball effect where eventually they'e all fighting each other again.
