While many distros already have this feature (generally via installation in /usr/lib/wine-<version> prefix or patching build-system), I'm opening in hope, that it's possible to convince upstream for slight modification of build-system, so slotted installation would be possible without patches or FHS violation.
It wouldn't be a slight modification, it would require fairly extensive changes. I doubt it would be possible to do this without making a mess of things.
