This only qualifies as a sane response if one has no ethical qualms about the Imperius curse. Which is a bit of a problem, because most sane people wouldn't like the idea.
Putting aside the sketchiness of the idea itself, it's flawed. If any zombie high on the chain dies or makes their will-save, every zombie subservient to them is freed, and has knowledge of the Grand Imperius Effort. If, before the experience, they hadn't had strong feelings either way about nonconsensual use of mind-effecting spells, they certainly will afterwards; everyone post-zombie is likely to oppose the plan.
I suppose you could ameliorate the first bit of the first part of the practical problem by sequestering high-level zombies so they don't die, and the rest with sufficient use of propaganda. This assumes that this program is endorsed by a quite powerful organization.
If we assume control of a powerful organization, though, it'd be more effective, and slightly less hideously unethical, just to sterilize all magicians and eliminate the "devastating, distributed destructive powers of magic" in a generation or two. Or write an Interdict of MerLarks to encompass all non-healing spells.
After devising a plan for a GNU world order, it's only logical to take the next step up into resilient W2W (Wizard-to-Wizard) networks: add a clause ordering Imperiused wizards to re-infect every 100th wizard they meet. This random crosslinking will convert the efficient yet fragile pyramidal hierarchy into a robust distributed graph.
