A bomber kit could be a fun addition to skywars kits it would utilize boomboxes.
The bomber kit would allow you to spawn with boomboxes or get boomboxes with each kill or something along the lines of that.
Hi! 
Welcome to the forums! I actually had the same idea for a kit in a game that i suggested, but it wasn’t skykits related so it doesn’t count as a dupe. Don’t forget to vote for your own post!
