IMO, there’s not too much of a reason to have them in a pack if they can be found (somehow) and made into a contract that can be replayed at one’s leisure. I did replay ‘The Deceivers’ and ‘The Prince’ (one of the hardest ETs) extensively in H2 (and feel I’ve come up with consistent and mostly safe strats for both).
I can’t recall if they’ve been found in H3 yet - doesn’t seem like it. 
'Guess I’ll check for those next time I fire up the game.
Obviously, the question is whether any reward should be given for completing if/when they’re available at any time. Maybe ‘Yes’ if you’re shelling out 
to play 'em.
I’ve thought that they should show a pic of whichever gloves you get with the suit since you already have the suit. That’d be funny!
