I have this idea that I want to reach MikeMirzayanov to help ICPC participants in their practice when using Codeforces.

It's simple, combine two contest to create a new one. I propose adding up durations of the two contests to get the duration of the new one, and the order of the problems any would do, better random actually, to simulate the ICPC conditions in a better way.

It would be nice to be able to save this new contest in some kind of cf user section, so anyone can see your creations.

Let me know if I can help, over and out.
