(German) Words do not work like that. First, it's called 'schlimmer', so -> "Verbesserschlimmerung". Second "schlimm" is positiv, while "besser" is the comparativ, so you need to swap these too: "schlimmer" and "gut". Also the genesis of the word works like this: "besser" -> "bessern" -> "verbessern" -> "verschlimmbessern" -> "Verschlimmbesserung" (better -> becoming better -> making better -> making better towards a worse state -> same, but as noun) So you append to the beginning, while keeping the existing prefix. If you want to end up with "worse" at the end, you need to start with it too. "schlecht" -> "verschlechtern" -> ??? But then "gut" doesn't fit, because that implies an absolute, that "schlimm" does not. Note, that "schlimm" does not plainly mean "bad", that's "schlecht". It also contains the notion of pity, guilt and impotence. That doesn't really exist for the opposite.
