I know it might be hard to get access to the roghts, but a Redwall based series of pops would be amazing. Start with either the book "Redwall" or "Martin of Redwall" and work from there?
It's a great idea and I'm very sure that there will be so much interested folks in collecting it. Although, there's going to be a very difficult challenge with managing rights to it.
Martin of Redwall is my favourite. It have been years since I collected it. It's still in my possession because I made sure to package it well. It's still in the box I purchased it in.
