Put another way, the only thing difficult about your request is the vertical cliff. The rest is reasonably easy. Unless you use world painter, though, getting the vertical cliff combined with the rest will be largely a matter of time and praying to the RNG gods.
I did the canyon search and gave the maps a whirl, they definitely produced the results as advertised but ended up being too 'artificial' for my taste. However they did give me a good idea of how to adjust my own maps to get similar results. On the fourth attempt I had some good luck and saw some lovely river gorges, interesting evil regions etc.
The key for the river gorges seem to be the following settings:
[EROSION_CYCLE_COUNT:100]
[RIVER_MINS:600:500]
[PERIODICALLY_ERODE_EXTREMES:0]
It'll cause a lot of failures, especially if you have other requirements, but increasing rivers and reducing erosion, even on a large map should give some nice results. Hope that may be of some help to others.

- I really am not looking forward to planning for this)). But as it stands you have a choice about how 'hardcore' you want to be in your defense.
