I did something similar to what you are doing.
I dropped to 50% time AND they let me move to Hawaii and work remotely. The plan was I would then drop to 0% in 6 months. But it turned out they needed me for a lot more than 50% time. It got very complicated but I ended up getting RIF'ed one month before retirement, with severance at the 80% level. Now they want me to do some consulting for them.
At any rate, it turned out well for me financially, but as far as ramping down my schedule it never worked out that way. I was always getting called into various little crises. But it was nice working from Hawaii where we retired to.
