The more I think about it, the better it sounds. All you would need is a Bed and a Bar, most times you could seat the retired capatain in a Cockpit seat with a Yoke and a set of throttles to hold on to and put a Basic T in front of him, I'm sure he would be content for hours.
You're not kidding about the young F/O's hearing you, at a recent sim session I was nudged to "drop dead" just prior to flare, after the F/O landed, he called for someone to come and take the dead guy out of "his" seat!
