Looks good to me, I'd use it.
One small little detail, I would move the 3 Shield Wall from Combat Jumping to Stealth. The end reduction in the set will do you more good on Stealth. Since Combat Jump has practically no end cost.
And since you have stealth , you might as well use it. I have the same on my farmer.
Only comes to about 2.5 % defense or something but 47.5% is better than 45%. And the Shield Wall set will help you reduce the end cost a little bit if you move it.
And if you do have endurance issues think about trying Cardiac Alpha instead of Agility
Edit: I think my statement here to try Cardiac as a general rule works if a build having end issues, but as a pure farmer build you would be better off with Musculature.
I myself run an end hog farm build, but have trained myself to keep Ageless going as I farm. Something to think about.
Also your base empowerment station has an increase recovery and p2w has amplifiers.
