No because there have been 30 years of patches, fixes and hacks put in place to work-around faults that have arisen and also to improve results from science instruments as better ways to get more out of them have been developed. The "old guys" would have to spend ages getting up to speed with the current state of affairs versus the way they left it. On top of that - assuming they are still in the industry - they will have moved on to more modern electronics so may not actually be as well versed as the current team are anyway.
