While I'm sure it would not be cost effective, monetarily speaking, to do this... now that implants can be stripped, is it not possible to increase the QL of an implant as far as you'd like (up to 200) by adding clusters with a high NP skill, and then stripping them out?
Note, I'm not saying this is worthwhile, just that it seems possible. Maybe it could be a party trick to impress your friends, or else a way to 'fine tune' an implant to a very specific QL. Or turn those QL 194 implants you find missions into QL 200 ones by adding/stripping a few faded clusters?
