The idea of adding a multi-media dimension to books comes up often, and usually gets shot down just as quickly as it comes up. The problem is that reading and viewing are totally different experiences - and people who are looking for one may not be looking for the other.
When I'm reading the last thing I want is multi-media - just as when my stepson is watching something, the last thing he wants is to have to read.
It reminds me of so-called "motion comics." For the most part they're just bad animation rather than comics with an extra dimension.
