I've already replaced lutris with Heroic launcher + proton and wine-ge a year ago.
Lutris install script already didn't work >50% of the time for me and battle.net always completely corrupts and messes up after a time on lutris and I have to reinstall it every few months, but has been going a year strong on heroic.
You can also always look at the lutris install scripts and install those components in heroic via winetricks. They were made by the community anyway.
