The risk having a Tikali haven holds is that of being frequently spied on by the Silent Imperium simply because the Silent Imperium tends to assume the worst until proven other wise.  The Silent Imperium may secretly have a pact with Terminus but is unlikely to ever acknowledge an open alliance.  Even Tikali who decided to set up a independent home world 'prematurely' end up having the Silent Imperium spying on them to a degree.  The Dominion is still out there after all, and you never know what plots they convene to finish what they started.

I don't think a secret pact would really work out; in the view of the Terminus it'd be healthier for the Silent Imperium to move on. Settle new worlds and stop being stuck in the past, and some such. Hell, to be honest some would probably pity the Tikalli of the Silent Imperium, viewing them as prisoners to their notions of revenge and letting the Dominion dominate their very existence. But I can still imagine the Terminus as letting the Tikalli set up, they're just nice like that. Plus any Tikalli would stick out like a sore thumb on a Simulacrum world.
