Afraid not - but it seems to me that the LSCM Unwrap is very close to getting it right.

For comparison, in the attached I'm using the left side of an aircraft canopy. The top left is an unaltered UV Map using the Remap / left function. The bottom left is an unaltered LSCM Unwrap. The top right is the same LSCM Unwrap just resized dragging the bottom box up to match the top left.

So close.... The LSCM just needs fill left right - rather than left right and top bottom.... (maybe just an option for the LSCM).

Hope that makes some sense....
