36 HOUR CHARITY STREAM? THOUGHTS?

Hi all, I am a silver 5 player in NA server wanting to get my smurf ranked and do something productive with the time i spend on lol. I was considering a 24 hour unranked-something stream for charity and borrowing viewers from more popular streamers, nightblu3 maybe trick, if i can get them on board (been subber for like 6 months each). But it just seems like its been done a few times to many, so I wanted to make it more interesting. I was thinking maybe that x factor could be time, so I could do a 36 hour stream for charity. There is a very good childrens' hospital in my area that is always looking for funding and I had done some work there within the last few years. Another idea was open stream like that but also you could go online and do a pay by the hour for my stream, like a marathon, and for every hour more I stream I make X more for charity. I think I'd run it from Sunday afternoon on, so as not to stream during lcs as i would have significantly less viewers. Thoughts? Questions? Comments? Feedback? Anything would really be great.
