Not sure how fun that'd actually end up being, to be honest. The spawn is tight, and you could easily camp besides it and push people out off the cliff, there's only one exit. It's pretty small too, and you have to go past the main route to reach most of the flanks (I think).
Although that doesn't mean there isn't a koth version of it, I'm just saying someone would have to put a fair bit of effort into fixing it up for it to be notable.
