Possible for a subclass
Doesn't not work, but I'd sooner it not be a subclass ability at all. And my personal homebrew levelling table is already a bit packed.
If I was considering where it (or something like it) could go for the 5E Ranger... I guess it could swap out Canny in Deft Explorer. Or be an additional option you can choose with Deft Explorer, if using the original UA set-up. "Pick one of these at 1st, 6th and 10th level", like.
