In general, this will/can/has the potential to bring in more activity, if it is organised properly, with a set date, and maybe something of a story behind it, not always, but still.
There are people who love pew pew, and this might interest them more. Then, as this becomes more and more gradual, it will start developing naturally, and there might come a time, when this event might not be needed to get those people raid each other on a frequent basis. As the raids become more and more prominent, people who are interested in RP, might join in too, who knows.
Overall, if handled with care, I can see this as a kickstarter for gaining activity within the Omicrons. I, along with some others who are interested in this part of the space, have had a few other ideas, relating to the layout of the Omicrons, one that gives little to no concern over lore, logic or anything, but is outright fun, and one that might make people dust out their titans, sabres, mantas, and bastets.( a very optimistic idea, but I am sure that it will work the right way.)
Still, my opinion would be that, consult the admins, devs, or whoever in that case, and let them do the forum posting stuff, inviting the players and such. They know how to get in more of the players, and the vets around here, let them handle this kind of stuff, they will have a far more wider contact list than we do, and they can be the catalyst in the first few steps of this maybe event. Overall, a good rough idea. Needs polishing and support from anybody who is willing to pew pew and organise pew pew.
