I hear ya, brother. But, remember -- it isn't at all necessary. I'm not convinced it's even the way to go. But, if someone had some inspiration hit them and they came up with 4 siblings that worked well together, then that could be interesting. My bet/hunch is they'll all end up individual. Don't stress the 'package' deal anymore. Do your thing, man. Love when I see you've made a new entry!
