Unfortunately AFAIK there was never any serious resources from MoMo/MoCo 
put into rewriting anything to web technologies.

One of the valuable things they did put resources into was creating and 
setting up the testing infrastructure. With your proposed start from 
scratch model all you'll get no test coverage at all, and that's really 
bad. Things just aren't that easy to get right in the details.
