Should I Do It?

Hello everyone! I had this idea, but I don't really know if I should chase it. So the premise is Death the Kid has a cousin, Dream the Clown, and he's going to start attending DWMA classes [Haven't decided why yet]. I don't really have a plot for it yet; I got the idea from an old proverb:

"Sleep is the cousin of death/ So my eyes will stay open until I take my last breath."

So my question is; should I continue with the story? And can you guys pitch some ideas to me for a plot?

Here's the character chart:
