Yes and no.
I've tried this.
Personally, I'd rather have my toenails peeled off.
You parry more often with -evasion gear. By more often, I mean you might parry 5 times in an hour instead of 2.
And the skillups work like a weapon. If you miss, no skillup (i.e. no parry proc, no skill up) and if you hit, you MIGHT get a skillup (i.e. if you get a parry proc, you MIGHT get a skillup). You have to pick the right mobs, too. At 97, you might like chamber beetles in Garlaige for this. If you're very lucky, in 3 hours of trying, you might get 1.2 parry.
Actually, you might have it a bit better. You don't have four tiers of passive evasion boosts to cut through, so you might do better than I did.
Best bet = get a healer friend, a low damage weapon or a trick staff II or something, as much -evasion as money will buy, and just let a chamber beetle beat on you. It's slow as hell, but good luck. And remember you have to be engaged to parry.
