Sad, the harvester/mower map was very clever; I never could imagine a map like that.
If you want some ideas you may want to play the Luminar's Fremen campaign or my own campaign; Fremen only have 2 campaigns, but mine campaign it's a baseless campaign (you don't produce units at all) but you may get ideas for those 2 and mixing togheter.
Luminar's make use of "black Fremen" and "rainbow Fremen" as multiple factions, and since you are already using Luminar's binaries to do your own campaigns, you can still reusing to make a Fremen campaign on your style with any ideas you may have for those guys; dunno, AIs deploying bases being allied Fremen factions that help the player; spawns/reinforcements from a near Fremen Tribe that help you or that attack you because reasons. Dunno.
Just remember that my campaign don't use moded files (the map will be too easy, since the Fremen are really strong on your modded file); but if you only want to go through the maps easily you still can use it.
Overall yeah, playing the Fremen campaigns can give you ideas mixing different campaigns or just 1 idea that Luminar or myself did for a small map you can improve it into a much bigger map or even multiple maps.
Ps: You know, the use of deviators to use on enemy units and using them to destroy his own base was something I never think about, and I have 2 maps in which I literally make the deviator the core of the map, but I never through on using them that way.
In the megadrive yes, in the PC versión I don't think so. The best way to really test any difference could be using an editor (I used to have Dune Legacy to do the fast editing, saving the .ini file created and then playing the map in the original game) and place both units in horizontal 4-5 tiles away to shoot each other.
