I thought as much (concerning it bieng too sci-fi). Still, I think there might be a place for it, albiet a small one. Hoarus seems ideal for a couple reasons;
1. Ban on divine magic. A nation that is banned from practicing divine magic might very well turn to more scientific pursuits. I also beleive there would be a kind of synergy for a godless realm to ignore the spirit in favor of the mind.
2. Hoarus has dwarves. If they had gnomes as well, it would be better because the combined efforts of the two would bring a good combination of industrialness and creativity to the table. Also, the dwarven affinity for earthen materials (metals) fits nicely into the concept (i.e. a tank would be made of metal, created from the "earth" nation).
3. Hoarus is a superpower, and thus could afford to create and sustain a military science research program.
Anyway, if it was adapted in Hoarus, it would be small (perhaps a company sized element) supported by the military science research program.
