Well, if you're backed up by professors, then this sounds promising.
What I would start with if I was working with this issue, is how to present the information for the students in the best way. At least for me, linear algebra and physics becomes way simpler with good visualisations/videos. If you could somehow make it easier for professors to present the content well, then you have a good start for a good website. So, all in all: Find out what makes people learn the easiest - I'm pretty sure there are some studies out there elaborating the way to teach students. If you make this way of teaching students easy to do on your website, I'm pretty sure that this idea might work out well.
