why would you want it to be removed? k is an important letter of our alphabet and without it, there'd be many words we wouldn't have any more.
I also agree with some of the others here, this thread is pointless and im surprised the mods haven't taken it down yet. how long has this thing been up anyway?
Anywho there's no reason to delete the letter K. Tons of people would have to spend money to change their names and there are animals whose species start with K. Ciwi, Cangaroo and Catydid don't look right.
Get rid of C instead. Get rid of Q and use kw in it place. Make a new letter for th (Or, bring it back I should say.). Also use F instead of ph. Like seriously.
