Hi,

As far as I am aware it's not possible as there are additional options that would need to be set during the compiling of the ROM itself. Also the version of ART of Kitkat and Android L are quite different, and trying to run the Android L version on KitKat would cause many incompatibles.

The version of ART in KitKat was an early implementation designed to give developers a taste of whats to come not as a general use feature for the public. As a result the performance in ART on KitKat and on Android L will be quite different, and it's unrealistic unfortunately to expect to see Android L performance gains on the KitKat version of ART. Keep in mind as well ART will keep getting tweaked and improved by the time the final version of Android L is released.

Yeah using directly the libart.so from Android L in KitKat sounds strange, but shouldn't it be possible for the devs to include the progress from Google into their source? Or are there parts of ART Google didn't publish?

In theory it's possible to provide this as Google has started to add components of the Android L preview to it's open source repositories (I haven't looked which particular components have been updated and hadn't been updated), however how well the complied sources would play with KitKat if at all is debatable.
