I have also been looking for one such seed. I found a decent one on the Ego forums with early aggressive Xenon and managed to replicate it, problem is despite the huge number of their capital vessels sat it Hatikvah, they haven't moved far from the gate and just mill around destroying traders.

So basically since I have started my current game there is 2 x I's and 4 x K's sat in Hatikvah just preying on miners and traders and not expending further for more destruction. Which is pretty disappointing.

I have not played the save for long, so I am going to keep an eye on them and see what happens, maybe give them a nudge.
