^^More people who have retweeted about the project: Kazami (DaizyStripper), MiA (MEJIBRAY), Z (R指定), Ryo&Nii (Girugamesh), Takeru (SuG), Mizuki (Sadie).
Kyoma (ex RevleZ) & Yoshi (ex Xepher) have retweeted it too but I'm less sure if they will be part of it. (I'm sure I'm missing out on other bandmen, too.)
The project is sure gaining a lot of interest (over 2K retweets last time I checked) and I hope this will be as promising as it looks.
