If you want me to be honest, Gaians and Planetform never had an event even remotely related to their causes or war with each other, but that's not suprising consirdering the huge activity both sides have... If there somehow would be enough people to set up one, I guess it would be a Gaian raid on Methyr-Tudfill Mining Facility in Poole or Planetform raid on Islay/Holmfirth.
Other than that, I'd like to see more pews like Dundee, maybe snub-only pews in Omegas, or something like the nomad material convoy event we had few months ago. I generally don't like to participate in Conn events, I find them way too "artificial". I'd also support attempts to inject some more life into OC/Sair war.
