HCO Additional Servers and Polling Engines

Has anyone redesigned their SolarWinds legacy infrastructure after switching to HCO?  I wanted to create a new HA SolarWinds infrastructure with additional servers and migrate our production data into it.  If you have, how many servers did you end up with?  Did you follow SolarWinds recommendations for cores and memory?  Since HCO gives us access to many new modules, I'm looking at using 10 modules at 26 cores and 34GB of memory per server.  Is this efficient use of resources or overkill?  Thanks!
