Take care balancing the loads across the phases - most EVs charge on just a single phase (L1) and it would be very easy to end up drawing 64A from a single phase which may be close to the limit. I have seen some charge point deliberately wired L2 to L1 to avoid this issue.

I suppose I could install 2x 11kW chargers (total 32A per phase?)

A 11kW is 3.6kW per phase, fine for the Zoe (and a lot of other cars) but if you have a 6.6kW LEAF it'll not be charging at it's potential as its only single phase. Whether that's an issue depends on how fast you need to charge.

I'm a bit confused. What's using the L2 and L3 if your house is on L1? Also are those typical, a snapshot, or maximum currents?
