Would the original sequel plot have been better?

In case you didn't know, there was another movie planned before "Shock Treatment" came out that was intended to be the sequel to the first movie. It was going to be called either “Rocky Horror Shows His Heels”, “Rocky Horror Picture Show: Part Two”, “Rocky Horror: The Second Coming”, “Curse of the Baby”, or “Revenge of the Old Queen”.

The plot was meant to take place 9 months after the first movie, where Janet, pregnant with Rocky’s child, is now a widow after Brad, who had become a professional go-go dancer in Las Vegas, fell to his death from a trapeze and was buried wearing only a rhinestone choker and six inch high heels. Frank-N-Furter is resurrected, while on his home planet of Transsexual Transylvania, his mother, the Old Queen, seeks revenge on Riff-Raff for killing her son. And later, after Janet gives birth to her son, Sonny, the Queen wants him, thinking its her grandchild, not knowing it’s Rocky’s.

No, I am not making any of this up. It was going to be made into a play first, and then a movie the play did well. Unfortunately, "Shock Treatment" was made instead, and this originally intended sequel never came to be, mostly due to the aging of the cast and the horrible ratings "Shock Treatment" received. Several failed attempts to start it began, but it was always dropped. One of the songs, entitled Frankie Pheonix, was leaked. It’s not entirely dropped though, but is stated to be in “development hell”.

So what do you think? Do you think the original sequel idea would have been better? Should it still be made?
