LoopPass manager is walking loop nest while invoking each loop pass on a given loop. If you update structure of loops then you need to let loop pass manager know.

There must be a good reason. 

In any case, see LPPassManager (it is a FunctionPass :), which provides simple hooks to record deletion/creation of loops. If that does not work for you, you'll have to update LPPassManager to meet your needs.
