Multiple subdomains and restricted IP problems on a single server loadbalance

I have 13 different subdomains under 1 domain name.
All of these sites are hosted on only 1 server. Their IPs are the same.
Likewise, I have another disaster server that is an exact copy.
Windows IIS is used in both environments.

My question is this; I spend 2 origins to run 1 domain name active/active on 2 separate servers.
Can’t I solve this problem with a single origin instead of purchasing 26 origins?

I’m fairly certain that you would need at least two origins, otherwise what are you balancing between?

This topic should give you some relevant ideas.
