Im am pretty much sure that it won´t work without considerable development 
effort. For the simple reason of KF5 versions of Akonadi + Akonadi agents 
being Qt5, while KMail 4.14/4.13 being Qt4. Also Akonadi in KF5 has switched 
to a faster binary protocol (of course, you could try the versions before 
that… but then you are out of support either…)

I never digged deeper into the source code than for a optimization of Maildir 
resource performance and that was with lots of help… but I am pretty much sure 
that Dan would advise not to try this.

I didn´t follow the interface issues thread… but I really wonder what you want 
to achieve by going that route. I´d rather recommend to help tackling whatever 
interface issues you faced with current KMail.

Thanks,
