Try out Storyteller, they're working on this exact problem: https://smoores.gitlab.io/storyteller/

Very cool, thanks for sharing! I'll follow the project and hope there's some way to get this running on Kobo or other eInk readers in the future.

It's using an oft-ignored part of the ePub standard, so I think all that should be needed for Kobo support is implementation of that part of the standard in KOReader.
