Startup Idea: Consolidated Digital Comic Book Reader App

Startup idea to develop a unified digital comic book reader app, allowing users to integrate and read content from multiple publishers and personal comic scans (.cbr and .cbz files) on a single platform compatible with iPad or Android.

I'm a digital comic book reader, but there isn't any really good software that allows me to use all my different digital comic book publishers to be used in a single app alongside my own personal .cbr and .cbz scans for either the ipad or android.
