Bruce,
My opinion, for what it's worth. I prefer firm and fast. That's what my course strives for, although our clay soil is not really best suited for those conditions. The "powers that be" at our club, which do not include me, got onto that idea somehow and have made it work as best as possible under the soil circumstances.
I am not going to answer the precise question you asked. I don't know an answer.
I think there is no magic bullet. "Soft and slow" is still golf, and many prefer it that way, for the reasons you note. I talk with many members of our club that wish we'd go "soft and slow" (with a lot more trees, too, like in the "old days" - except that in the really old days there were virtually no trees, or watered fairways, for that matter).
Accept that the process will be arduous. Take it easy and build support slowly, quietly, carefully, and then, wham, "take over the board". In all likelihood this will be a many-years process. If you are able to convince today's power-crowd to go firm and fast, please let us know. You will have performed a miracle.
An obvious alternative is to find a club with a course maintained according to your liking. Also, obvious, you've thought of this alreadly, and it is not a practical solution.
