2*? Relocating the aft stab attach would be what needs to happen to do that. I think my own -12 had that much surplus trim available. No matter, I was talked out of the mod by a guy who knows a lot more about -12s than me. And that's part of why I thought -12 wings on an -18 airframe would be a fun E-AB project. But now, 10 or 12 years later? I'd just buy a 3-place Cub airframe or an SQ-12 if I needed a 2-place rear seat. I built the Rev instead. The baggage door makes a wider seat unimportant to me.
