Bent arms is in some ways a good idea that is far from new, have seen them on heeps, rovers, etc for years. My original plan was to make a set, it’s easy, bend a tube that’s large enough to fit over the stock tube, cut the stock arm with a couple of inches of tube sticking out from the bushing holders, weld the ends into the new tube. But after watching several rigs on the trail with them, I decided to go with stronger straight arms, for these reasons:
1, I have never hung on the arms, always the brackets, have always slid nicely on and off the arms.
2, On a few occasions I have seen heeps get hung by the arm sliding on a rock until it got to the bend and not being able to pull over the steeper angle at the bend. In one of the cases, part of the rock hit the axle tube, if he had a straighter arm it would have lifted the axle enough to clear.
3, The relatively shallow angle of the arm raises that corner of the rig and/or compresses the suspension as it slides up on an obstacle, helping to lift the tire onto the obstacle.
4, On my rig, there is a sway-bar next to the arm and a shock near by, both are much more exposed with bent arms. They take enough of a beating now, but are be pretty much defenseless with a bent arm. I would rather beat a stout arm on the rock, than an expensive shock.
5, Why bother? My stockers were bent almost like yours and like you say when bent they don’t hit as often, so aren’t very likely to bend more?

Yes, I know, it was a joke, when bent that bad, the stock arm becomes too short, pulling the axle forward, this became a clearance issue when the 37” tire went on and my sway-bar and shocks were taking a beating, so had to do something.
Yours were 1”x 1/8” angle that didn’t go to the ends, mine are 1.5”x1/4” angle, full length, welded to the bushing holders on both ends. They probably aren't bomb proof, but have taken a beating, Moab, at least 3 Payette Draw runs, 2 with small groups where plenty of optional obstacle play happened and tons of other trails. They are beat-up but not bent, tested and will support the rig on them. Not a bad result for some scrap angle and an hour of time.
