What PJ said. The fact he felt the need to make parts, and modify parts, to make them work well says a lot.
0 pressure in one side, way too little in another.. means they aren't coming out tested of wherever they are made.
In any case, what is "too much"?
It's true I wont be spending a grand on any of my street bikes for rear suspension, but I'm glad I spend at least a few hundred. My street riding is somewhat 'spirited'. I do reach the top 10% of my suspensions abilities often enough that having poor shocks is.. well, dangerous.
I'd rather have a larger margin of safety for a couple hundred more bucks than "welp, guess I found the limits of THIS particular set of shocks" as I watch the bike travel away from me on it's side at accelerated speeds.
If you have a lathe, the experience, and the time to do what PJ has done, go for it. If not, I'd say pass.
PJ, you could always buy a few sets of these, do what you've done to them, and sell them for a couple hundred bucks. I'm sure with your modifications, they are at least on par with the non-rebuildable hagons, and have the ability to be rebuilt, and they have 'the look'.
And it's not just an 'ohlins' sticker on there...
