Has Tesla Considered a "Dedicated Regen" battery?

Today I preheated the car for 10min prior to departure. I also had it charge for an hour before leaving. This is with a 3500W level2 charger.
Outside air temp was 44 degrees.
I timed it with my phone: No movement/reduction in the regen arc for 22 minutes! At 41 minutes, the regen arc was gone.
At 55 minutes my trip was complete. So I had full regen for 14min of a 55min trip, and at 44F degrees.

3500W is not going to warm the battery much. 10kW does a decent job of it.
