I plan on running it without those, perception especially. It forces one to be very descriptive as GM, and I think that's a great opportunity to grow. Maybe you can try it out first as well and only add it if it doesn't work. But of course this is just a suggestion, it's your game after all.

You really don't need to. You can do those things using the existing skill system if you need to. Just make a 3d6 roll under the difficulty you decide (i.e., for checking if they know stuff: 17 for common knowledge, 12-4 for less well known stuff, 6-8 for very esoteric subjects).

Or you could just give them the information because it's more fun.
