I would certainly like to include it. The translation included in Sisterly Lust is a fan translation, so I rely on the work of others in this case. I don't believe there are fan translations of Tales From The Unending Void in existence at the moment, if so I'll be sure to include them.
That would be awesome! It's a lot of work though. If you send me an email at perverteergames@gmail.com I could set you up with the necessary translation files.
