for the matched lenses I thought I'd just get of the same folder and use one off each, or does it need to be more precisely matched?
coverage shouldn't be a problem because it will be a 6x9 (probably) lens covering 6x4.5

and PE, thanks for the heads up, I won't bother with the tilt then - less work too now, I won't have to build another bellows and can save the material for another LF.
