Doesn't work for me - for some reason bash is not picking up those
changes in my $HOME/.inputrc.

But this looks like a great way to achieve what you are after. One
problem with the script I posted is  it won't handle line-continuation. 
Eg.

   find . |\
     wc

But your method should handles this, as long as you use Alt-k for all
but the final line.

Looks like READLINE gives you a lot of powerful features here. 

Cheers, Ben
