Bumping this (wrongfully abandoned!) thread- I just got into the game and instantly thought they would work perfectly with scape. You guys have done so much legwork already that it'd be a shame if this project was dead
I ran the large hollows as a unique squad with a leaping power a la Kon-Tar-Na, which seemed cool but I think they were a bit overcosted (5M-1R-4A-5D @ 100pts). I also tried the SKs you guys designed- super fun! They play like a hardy common squad that has some versatility with the activations. I think they may be overcosted as well though, sinking 300 pts into 6 figures with 1 life each means it feels pretty bad to blank out. I think the swordsmen are deserving of another power, too- maybe giving them Deadly Strike and lowering their attack to 3 or 4 would work?
I love the Sentinels btw- super thematic and their movement on your opponents' turn seems pretty balanced.
