first of all, please add more details to a suggestion and make it more serious, suggestions like these just push away the serious ones.
second of all, as mentioned above, CC is mainly a minigame server, skyblock is obviously not a minigame but has its own special twist, that simply wouldnt work in factions. when it comes to making the server bigger, it wouldnt be too effective since there are a lot of faction servers already and a lot of people dislike the gamemode (including me).
obviously a no from me
