Is fuath leis na heilifinti an zú
The structure for "X hates Y" is Is fuath le X Y.
You can replace fuath (hate) with maith (like), brea (really like) aoibhinn (really, really like), etc.
In the same vein, you have is cuma liom for "I don't care" or "It's all the same to me", but it doesn't include the object of your approval or disapproval.
Specifically using an apostrophe probably would not be the best option. There is already a long history of people anglicizing the fada as an apostrophe instead of as a proper diacritic, such as in any last name that starts with "O' ".
I'm not saying you have a bad idea at all -- I would love to have more experience with the traditional font. It's just that that particular solution would carry some baggage along with it.
