Being candid, I really don't expect to see the 9-Bin reinstated in Buffers, sorry. Fritz offers a workaround, and Kane will no doubt suggest some alternatives, but really - although I know it's not your preferred approach - I think you'd do yourself a favor to take a second look at LiveGraphics. From what you've explained, a single LiveGraphic would dramatically reduce the effort you're going through to compile individual animation effects for every guest for every show.
Having created one LiveGraphic (or using one of samples provided), it's a simple matter to click one of 16 presets to update the metadata - really just like you're doing now in the 9-Bin except in a list. Having done that, with one more click (or keypress) a macro can perform an animated intro of the title, hold it as long as you like, and animate it back out again. If you prefer, you could assign in and out macros to your DSK's tally on/off and do pretty much what you're doing now, although this is a bit 'clickier'. This really seems like far less work all around, and yields a nearly identical result. You'd have no need to resort to After Effects or ASC again at all, unless you decide to update the base LiveGraphic in some way.
I'm really not seeing how this is more work to create or use, or any less flexible. Editing Data Presets is a lot faster than creating a unique effect every time you have a new guest, and can be done on the fly. And there's really no difference when it comes to modifying colors or other elements of the graphic, except that with a LiveGraphic, you can recompile the revised effect once, instead of doing so for every new guest.
This all said, there's more than one way to skin the proverbial feline ...
