This is more guesswork than actual facts. Personally I would go for HyperPro's or Wilbers rebuildable ESA replacements. I love to adjust my ESA on the fly and at least with the Wilbers you don't have to sell the house to buy them.
I think you are right.
The ESA factory shocks are replacable with Hyperpro ESA shocks, which they just move the BMW adjusters over to the Hyperpro shocks.
Alternatively, there are replacement shocks without a remote preload adjuster. These have preload adjustability, but it is awkward to get at and requires a spanner wrench.
A Remote preload adjustable shock will have a knob that is connected to the shock by a length of hose to adjust the preload much more easily.
See the preload adjuster on the frame?
