There are some specifications for this kind of thing already, e.g. 
multipart/related (RFC2387), and the derivative MHTML (RFC2557).

In HTML5, this can be somewhat achieved using the offline application 
cache feature, with a cache manifest. But the right solution to address 
the problems with MHTML are to develop a new RFC that addresses the 
problems with MHTML, IMHO.
