Swap out option

We had 2 members go crazy and had to report them for Racist Language etc,
they are on our map and in the upcoming war.
a Swap Out option would be nice to replace them with Equal or Lesser Members.
the computer could give the leader the options and he would pick.
limited times and number of spots and only on Prep Day

.... Better punishment than a ban ... Knock them back One TH Level

A swap out option would be amazing. I'll get a war started with another clan and then swap in all my th10s for my th5. Way to think this idea out. Love it.
