You will have to offset the value of two years of healthy retirement against the opportunity cost of acceding to your director's request.
Just one thing....you cannot buy time. Especially healthy retirement time. Once it has passed it has gone forever.

To the OP, I had a similar decision. After rescuing a project, my management let me know they would be fine with me changing my mind about retiring to continue to manage the project. I could easily sustain this for 2 years. The work for me would be simple and fun, the main downside was a relative increase in my traveling (somewhat offset by the ability to take DW with me on some of the trips).
Another 2 years would mean:
- another $200K to save and invest (our savings rate was already over 50%)
- Megacorp health insurance at less than half of the retiree rate, about another $15 in savings
- Pension would have increased by $2,000/year.
- No change in SS, I had already hit the maximum benefit.
But, at age 60 and in good health, time was much more important to me than money. We had enough for a more than comfortable retirement at a target SWR a little over 2%. And with good health, I could wake up every morning and choose what I wanted to do - but with zero guarantee of how long that would last.
So I retired, and have been more than happy with my decision. My first 2 years of retirement were worth far more than if I have kept working another 2 years. And it keeps getting better
