This has been discussed on the DB Class 60 withdrawal thread recently but DB have confirmed they are converting several of their Class 66 locos to have a higher tractive effort, allowing them to fully replace the Class 60s. With the tugs already seemingly withdrawn, DB have confirmed via a post on Facebook that the conversion work has started:
Our colleagues at Toton have started work regearing ten Class 66 locomotives to give them a higher tractive effort. This will ensure they can pull some...

I thought I'd create a new thread for this to track the locomotives being regeared and entered into service, as well as hopefully getting some technical info about the new tractive effort of these locomotives (IE if the locos are literally just gonna be same spec as Freightliner Class 66/6s which looks likely given the new numbers and 66/6 being written on the side of traction equipment in the DB Cargo UK video linked above).
The locomotives to be converted are (according to a previous post in the DB Class 60 withdrawal fleet):
This table hopefully can be used to track the conversions though of course loco numbers can be swapped out if locos earmarked for the conversion are changed.
