Always had the impression Cocolia was simply in charge of managing the unstable and unpleasant Welt clones (who literally nobody in AE liked) because she's the one running the ruthless "dirty business" in the outfit (her prior spook career no doubt coming in useful there) - the creation of such would seem like it falls more under the R&D departement which is Ein & Tesla's portfolio.
The Orphanage would seem like a pretty logical place in which to raise a clone you *didn't* intend to use as a disposable attack dog, tho, assuming the other bigshots actually trusted her enough for it.
