i believe you need the deodexed stock rom for the switch to work
Makes sense, since ODEX files are optimized for Dalvik run-time.
Why didn't I think of that?!So CWM or TWRP backup and deodex (or vice versa), then switch to ART VM, then wipe Dalvik cache. I think I'll pass until more is uncovered about running ART on KitKat ROMs.
