To be entirely honest, I don't think it would work;
- 24-48 hours is not a long period of time. Making assets and combing them isn't long enough - especially now that schools have started back and people have work.
- IiaW and the Duo Dev contests were "time consuming" enough. Iiaw is infrequent, so people can use this challenge as a "break" from their projects to work with something fresh. Duo Dev made you work in a pair and built teamwork and cooperation skills. Both of these are infrequent also.
Having a contest that pops up alot would discourage people since time constraints and the fact some devs would find it more of an "obstacle" to their own games to bother competing in often. I'm assuming from alot of recent status updates also, not many people have free time (alot of people who enter the other contests mention they made there games in a few days instead of the full time period, so that tells you how tight some people are with free time).
Also, who would supply the prizes? Having two contests a month would require a fair amount of prizes (and money if your buying them). I understand donations are a thing, but I doubt you'll get alot of donations each time the contest is held.
I don't think it's a bad idea, per se, more realistically, the forums are quiet lately and we already have 2 challenging contests set up so having an "indie in a night" would be way to tight a time frame.
However, I have seen this challenge done bwteen some Youtubers (RPGM ones atleast) and they said they had fun. So this could work out, but if you do want to do it, I suggest also reaching out to other forums to ensure you have a wide audience before deciding. Some people may be only free at weekends and would find this fun. Some may be to busy though, and can't participate. Won't know until you try huh?
