In my mind, this is something that is mainly implemented in the editor to give beatmaps a whole new challenge, but also has toggle functionality like mods do (HR, FL, HD, etc.), which means that the challenges would either be enabled or disabled. What this mod does is (almost) totally up to the mapper per beatmap.
SPOILER
- Set a section where you must not miss any notes, or else you fail (similar to SD, just in a small portion of the beatmap. Or large, it's up to the mapper after all!)
- Alternatively to the challenge above, there could be a set number of notes you are allowed to miss/mistime before failing.
- Set sections to have different mods forced onto them, as well as their score boosts. This does NOT allow the difficulty decreasing mods, DT/NC, or the special mods (Autopilot, relax, etc.)
- In addition to the conditions above, for mania, can't force the beatmap to switch from 4k to 6k for example.
If anybody thinks of other challenges that are reasonable and good, I will happily add it to the list!
SPOILER
Q: Where would this toggle be located?
A: I think that we can all agree that this belongs in the mod selection screen.
Q: How would this be implemented in the editor?
A: Right now, I'm thinking of two possibilities. Either we implement it as another tab in the timing panel, or we make a whole new panel within the editor. If we go with the latter, it might be best to do it in timing as well, which leads me to believe that the former option is the best.
Q: How would we implement this from within the editor?
A: The best thing to do in my opinion is to have commonly used presets in a drop down box that we can select from, and then numerical inputs for challenges like the number of misses allowed and etc. Also, for the difficulty increase mods, we can have check boxes.
Q: What if we want to overlap two challenges, but have one start in the middle of another?
A: The most likely option for this would be to implement something similar to inherited timing sections in the timing panel.
Q: Do you have any ideas for what challenges should be considered unrankable?
A: Well, I don't think slapping on HR, HD, and FL all at once is a good idea. HOWEVER, considering that technically, this is in itself a mod, it could be considered between the mods for the specific situations. You can practice this kind of thing without the mod anyway right? This kind of thing should really be left to the mods, but I think that not a whole lot could be considered unrankable as long as two(?) difficulties have reasonable ones.

I thought about this last night, and realized that if there was a challenge that required you to say, not miss anything, you would get no reward in terms of your points! So, I think that for every challenge mode completed, the points you earn from that section must also be multiplied! By how much, however, is the question. One idea I've got is that the intensity of the challenge should affect your multiplier (within the challenge section). If this gets any priority, and a mod gets input, I'll edit these last three lines with how much a score should be multiplied by.
That's it for now! If I need to/should add something to this, someone let me know and I'll get on it!
EDIT: Added the section for scoring issues.
