I would very much like to know if there is. AFAIK you can't complete the
upgrade without downtime. Two switches with even just rebuild version
differences can't live together in the same stack, so there's no chance
of upgrading without significant downtime.

We're starting to use 3750E with 10G trunks in between them instead of
Stackwise. This makes it possible to upgrade practically without
downtime.
