The graphic mod is quite simple to be manually installed - and yes, I've been diving into RTW/EB/other mods files that I feel rather comfortable when looking for something, so there was no problem for me to do that myself.
And - the mod is fully save game compatible.
I've preserved old EB icons to be used in the future - maybe naval blockade? Now I'm delighted with new ships and not sure whether go back to EB ships... but who knows...
