I'm now using
    \newcommand{\khat}{{\rlap{$\mkern7.5mu\hat{\vphantom{x}}$}k}}
and
    $\khat$
and things look about right.

No doubt I should play with \mathchoice and make it look "really"
good.  But then I'll buy the Lucida fonts and have to do it over.... 
I'll wait until my next paper is due.  ;)

Thanks for all the help!
