Er, what? You can run TEW with another system and still ‘highlight and exemplify’ the tropes. Using SotDL would allow you to run the whole adventure while only really changing the combats.
The post replied to claimed¹ that
fidelity to the setting is not important to the adventure, not that
it can't be run in other systems.²
If you choose a system which is built inherently counter to the tropes, then either
- you're not going to be using the system unmodified or
- you're not going to be running the adventure with the setting tropes intact
Choice 1 means the benefit of that system switch becomes irrelevant
Choice 2 can break the adventure, and generally damages the experience of adventures based strongly upon the setting tropes.
TEW is VERY strongly tied to the setting tropes.
As an exemplar: Doomstones can be run almost unmodified in D&D by use of the same named monsters... as a low-level adventure.
D&D Module B2 can be run in WFRP the same way, but note that it routinely kills starting characters.... some of the more social B and X adventures can be ported in similarly.
Meanwhile, Lichemaster really doesn't work all that well by this port method... a D&D cleric makes short work of the badguys, and the whole cringe-worthy threat is lost... Because the mechanics violate the tropes. (Not to mention, there's no real good direct conversion for rat-men/skaven.)

²: It can, as is evidenced by peoples suggestions, including my own, of using WFRP2 or Zweihänder.
