It's a good idea, but it wouldn't work very well. Streamers and people who do carries in general would just not purchase the boons and just reset their passage upon completion of the carry or failure of the carry to stay in the lower tier playlist for easier games. You might ask, "What about their lighthouse trip?" Those that do carries all weekend have(I'm just going to assume)have been flawless so many times that they don't need any of the gear going flawless has to offer anymore. If they do however, they can just wait until the last day to do it.
