I don't think this is good idea to split it.
All the time when you split development to different trees/configuration they start
to diverge and then you just need to spend more a more time to manage both.

My strategy will be to add both configuration together.
It will have also demonstration purpose to show up differences.

If you want to use two boards you can.

Thanks,
Michal
