Thanks very much, NickName!
If anyone plans to play the Deep Vistas maps with SWM (the files I provided for Vassal have the SWM terrain lines), here are my suggestions for handling elevation. They've not been playtested and may prove to be abusive or overly complicated in a skirmish environment, but if anyone wants to try a change of pace and see how they work out, I'd love to hear an after-action report.

These maps were originally designed for a D&D campaign, so a couple of them include a feature that the Star Wars miniatures game always steered away from: elevation. I've used purple lines to indicate borders between squares that are separated by an elevation shift. If you find yourself using these maps in a Star Wars miniatures skirmish, I propose the following rule treatment:
1) A solid purple terrain line indicates an area of higher elevation next to an area of lower elevation. If it lies between two miniatures on the battle grid, the following rules apply:
A. The miniatures are not treated as adjacent for any game effect.
B. The miniature on the higher elevation (as indicated by the map's artwork) ignores any cover that benefits a target at a lower elevation.
C. The miniature on the higher elevation gains the benefits of cover against a target attacking from a lower elevation.
D. A miniature at the lower elevation (other than a miniature with Flight, Force Leap, or Wall-Climber) treats a solid purple line as a wall for purposes of movement.
E. A miniature at a higher elevation may move across the solid purple terrain line, with the following effects:
1. The miniature must end its movement after crossing the line.
2. The miniature immediately takes 10 damage from the fall.
3. A miniature with Flight, Force Leap, or Wall-Climber ignores these restrictions.
F. Any line drawn between two areas of low elevation that crosses one or more solid purple lines indicating a high elevation in between is considered blocked.
G. Any line drawn between two areas of high elevation is not effected by low objects at a lower elevation.
2) A dashed purple terrain line indicates an area of higher elevation over an accessible area of lower elevation. It follows the elevation rules above, with the following exceptions:
A. A miniature at the lower elevation does not treat the dashed purple line as a wall, and can freely move through (under) the elevated terrain without restriction.
B. A miniature that is completely beneath a piece of elevated terrain can not be targeted by a miniature on the elevated terrain, and vice versa, if the line of fire drawn between the two does not leave the elevated area.
C. A miniature with Flight or Force Leap that moves across a dashed purple line from outside of the elevated area may choose which of the two elevations it enters.
3) A dashed red wall line is treated as a wall by characters at the lower elevation, but not by characters at the higher elevation.
