Which site, ECN-2.com or Double Exposure? Dbl-X uses a cine processing machine. ECN-2 did process by hand, when they were functioning.
I don't think a minilab would be able to be modified, at least not to incorporate rem-jet removal. It's at least partly a mechanical process…something needs to knock that stuff off the back of the film. As for the chemical part, perhaps. I think the steps are roughly the same as C41, just the chemistry and times are different.
