Somethings tipping & whilst you might expect the static pad to do so (with the adjustment screw being the pivot) I am surprised that both sides have been affected. For such wear to occur, the clearance between the pads & their housings must be 'there' but I suspect something else is amiss.
My reasoning is that both pads tend to spin a little in their housings under just a little load until full force is applied. That used to concern some racers, looking for every advantage, & the moving pads were shaped to fit the housing with @ least one ear to counter rotation. Meanwhile, the static side would not have an adjuster fitted, just large shims of various thickness that fitted snugly.
I'd look @ the moving piston of your slave unit because that may be the issue, though don't discount there being an excess clearance issue with that, too. I have no experience of the clip-in slaves as I've only ever used screw in type, but tipping seems a distinct possibility
One of the design failures with the standard disc brake set up is the actuator retaining circlip.... Because this clip is only partially enclosed, it doesn't distort concentically. It cockles over a bit and applies an offset force to the moving pad, resulting in uneven pad wear.

...but why would this happen on an inboard that has been converted to hydraulic, as per the original post? Happy to be corrected, but all hydraulic conversions I've seen use a threaded actuator, removing the need for a circlip.

I can't help with the issue but I've had great results with OEM disc pads. They're hard to find, but IMHO it's worth keeping your eyes out for NOS ones.
