I've just submitted (as 'bug' 29404) a patch I've been using successfully
for a few years now.
There was also a brief discussion on this list back in November, with a
partial patch which changed the proxy source address to be the same as the
enclosing VirtualHost's listen address.
My patch adds a new per-VirtualHost configuration directive
ProxySourceAddress, which takes a single IP address. This needs to be an
existing interface address on the local machine, of course, otherwise the
bind() call will fail. It'll accept any format understood by
apr_sockaddr_info_get(), including a hostname, although that's probably to
be discouraged for performance reasons if nothing else (and it may not do
what you expect if a hostname resolves to more than one IP address!).

With the patch, your setup could be configured as follows:
<VirtualHost A>
ProxySourceAddress C
ProxyPass / http://E/
</VirtualHost>
<VirtualHost B>
ProxySourceAddress D
ProxyPass / http://F/
</VirtualHost>
