What would that even mean? A package manager is for tracking and installing dependencies, and putting things in the right place in the filesystem. AppImages bundle their dependencies and don't expect to unpack into a filesystem, you just put them in an /apps directory. Do you just mean that you want a repository of AppImages to search? Otherwise your "package manager" is 'curl $APPIMAGE_URL > ~/apps/$APP_NAME' and 'rm ~/apps/$APP_NAME'.
