Unofficially, I would say no. Because Transformed monster counts as an Item, you can't attach it once its an item. If it was a monster, and then ransform, that's another story. Here's proof of why I think not. Keep in mind that Ultimate requires the card to be a Buddy Monster.

Q. If a monster with 『Transform』 or 『Ride』 is equipped, how is it regarded as?

A. When there are power, defense and ciritcal values, it is regarded as an item with defense. That card will also have the abilities and the attributes of the card.

 And..

[BT04/0036EN：Immortal Sword, Durandal]  Q. When this card is on the field, is "Immortal Sword, Durandal" considered a buddy monster?

  A. No, it is not. As "Immortal Sword, Durandal" is not a monster, it is not a buddy monster.
