As this would be a custom modpack there wouldn't be an existing popularity to bring in players. Eventually players quit or they move on to another of our server, or they get banned, it's inevitable to run out of players. We've had plenty of custom modpacks servers that haven't worked out for various reasons, the thing is that a modpack like this would become populated by the network's regulars and that would be about it. Playing around with adding a new server just for this gimmick and having a custom modpack to showcase it I can't see that working out in the long run. As every player would also have to add the mod separately.
As stated, adding a mod to an already existing modpack would hardly be possible, or atleast it would come with alot of hassle.
