brew install --cask --no-quarantine gcenx/wine/wine-crossover

This will install Wine Crossover into /Applications and function as the official brew cask would.
The --no-quarantine flag is required so brew skips the quarantine flag that causes Gatekeeper to believe Wine Crossover is broken.

wine-crossover is not an upstream package.
