No, a 6x12 with EVM12Ls would be a) incredibly expensive and b) about 80-90 kilos. Good luck lifting that in and out of a car every week for band practice and for every gig!
I've seen those 16x12s (on youtube, not in person), they look very fun, but you'd really want some serious power to drive it - otherwise you're not really getting the cones moving! But don't even think about the cost or weight of 16 EVM12Ls!!!
