A thousand years of effort might be able to "domesticate" the bumblebee and make it produce something akin to usable amounts of honey - but unlikely to be worth it.
Bumblebees are being "domesticated" to some extent, for pollinating greenhouses, but they're used as labor animals rather than food.
Someone domesticated foxes in 20 years https://en.wikipedia.org/wiki/Domesticated_silver_fox , so perhaps it's possible to domesticate bumblebee in a few decades - but unlikely to be worth it.
