Unfortunately, at this time we do not have a rule that will function this way with different SKUs.
Please note that there are Discount Rule Types for:
"Buy X, Get Y at Z Percent Off - Item"
and
"Buy X, Get Y at Z Percent Off - Group"
"Buy X, Get Y at Z Percent Off - Item" would allow Buy 6, Get 6 at 10% but only on the same SKU.
"Buy X, Get Y at Z Percent Off - Group" would allow Buy 6, Get 6 at 10% but with a mix of SKUs.
You kind of need "Buy X, Get Y Percent Off - Group" as a rule, which unfortunately doesn't exist. I have added it to our suggestions list on your behalf. You could maybe try "Buy X, Get Y at Z Percent Off - Group" with 6, 6, and 10 to approximate it though.
