"Most efficient" for what purpose?  There is more that one might do than just 
duplicate bitcoind exactly.  I can well imagine storing bitcoin blocks parsed 
and separated out into database fields.

If.  What if I'm writing a client and don't want to store them the way 
bitcoind has?

Except the alternative is no schema at all -- essentially it's just give 
access to a file on disk.  Well, that hardly needs discussion at all, and it 
hardly needs the involvement of bitcoind, apache could do it right now.

I don't think it's a "rewrite".  The wire protocol is only a small part of 
what bitcoind does.  Adding another thread listening for HTTP requests at the 
same time as on 8333 for stadnard format.

Anyway -- I've obviously misunderstood what the idea behind a HTTP protocol 
was, and it's not like I was volunteering to do any of the work ;-)
