I've seen people try it, and might not not be technically impossible. But it's certainly highly improbable. To not have to rare fish escape typically requires 225 skill, what that means is if you have 160 skill (75 lure, 75 base, 5 pole, 5 thread) you'll be 65 points short, that means almost every time it will get away (not sure the exact odds). I'm not sure how much longer it might take, but it could easily become 18 or even more weeks on average rather than 6.
I have not heard of anyone successfully catching it at 160 skill, some looking up for how the odds work might add more illumination. This is essentially how I had it explained to me.
