Yes, but if you happen to fire "the wrong" people it can take a while till the remaining one understand that component well enough for a hot fix, which for the original team had been easy and if ops are wieder to the specific dev team one can assume there are a few components with little attention now in the mix.

Depending on what you want to do. But it's unlikely you can fire 50% after a weekend in, even if you are willing to let quite a lot of projects die.
