It would seem like it would be possible, but make sure you upgrade neopsycho cat and castaway cat as much as possible. Those two are critical to success. Also, make sure you have as many treasures as you can get, they most certainly make a difference.

If you had to try to get a true form, try to get macho legs cat. He can be really helpful for ITF. Also, getting an anti-alien uber like the Dark Heroes can make a huge difference (but it is not necessary, at least for chapter 1).
