Cackling Rosie - that is a good name...
It would be. But it wouldn't be very nice

We named our route Cracklin' Rosie (did you skip the letter "r" in your spelling on purpose?).
And to be clear, these are names I gave. K.C. has been kicking ass as a mistress of mud for so long that I thought the name "Kat Pinnacle" would be appropriate and fun. From there Neil Diamond's song "Kentucky Woman" was an obvious route name, and why not use two of his other great songs for other route names nearby?
BTW, if you climb Cracklin' Rosie, you'll see that there's good cause for the "cracklin'" part of the name (notice the no stars?). But it was worth doing; it does end on top of a previously unclimbed pinnacle.
