Hello Chris Darrow:
Thank you for using our community.
Unfortunately there are currently no plans to add Kinetis E support in KSDK.
For this family NXP has the next software options:
1) Processor Expert drivers: Processor Expert is integrated with Kinetis_Design_Studio. Processor Expert projects generated in KDS can be also used with IAR or Keil:

2) There is a package with baremetal drivers in the next page under "Downloads -> Device Drivers":
Freedom Development Platform for Kinetis KE02|NXP
Best regards,
Jorge Gonzalez
