Multiple domains same website different Titles

Hi There,

I have searched for lots of options to tackle my problem but somehow I can’t get is working. So here is my problem:

I have serveral domains that show the same website with the same content but just with different titles and logo’s

So I can use multisites to put them all in but when a use a feature like share post on all multisites it will copy all images and attachment. And with more then 15 domains it increases the disksize unnecesary.

I have come up with other solutions but somehow it did not workout. And syncing the content between the installations is just useless with so many double images and attachments right?

Can someone help me and give a a suggestion with or without multisites?
