Adding in the option to set skulls for various missions, strikes, or raids would be great. Our group was talking tonight about how interesting it would be to even get the chance to turn modifiers on during PvP play. Think about a no-hud modifier in the Crucible, but with a big payoff for winning or even a small one to simply complete the game... Say, something like an increased chance of a legendary drop, or even more marks or XP. Even the idea for strikes and raids sounds excellent. Imagine playing the Vault with all the "skulls" active... No hud, increased movement, grenade throws, and armor on all enemies, burns of all types, juggler, light switch... All of them, if you want, but it has a huge payoff if you complete it. Just a few thoughts on a possible way to liven things up and make some of these missions fell a lot different. We've played through the Vault 7 times now, and I know people who have done it way more times than that; this would be an easy way to really make things more interesting for the same raid.
