I'm pretty sure that people that know how to actually edit and then use a client.exe has a copy/knows how to get a unpacked client.exe.
And for those who don't know how to edit it; they don't have it. So, you are like asking us (including me) noobs to beg you/other people to teach us how to edit it for use?
PLEASE TEACH ME HOW TO EDIT THIS THINGY!!!!
