I was the one who told you about staying up for that long, and it was Stephen LaBerge's version of it and it helped many people to MILD.
Lucidipedia used the same method of staying up for a longer time (1 hour) and then motivate yourself until you reach the peak and then just fall asleep.
But for WILDs I think it would be better to stay up a shorter time, although you can only find out yourself.

I also had a bullet proof technique "the timer method", I had 5 lucid dreams 5 nights in a row, but then suddenly it just stopped working and it only works when I take a break for a few days and then do it again. So I would suggest you to do other techniques on weekdays and your special ones on weekends.

But you can also just see if it works if you stay up for a shorter time.

Good luck!
