I am currently working a hax thing for DBH, and I have gone through the important ones. But if you are free, would you be willing to quickly grab and translate Xeno Vegeta's cardsss? There could be some abilities there we could add to his profile.
Freeze Attack isn't something the characters do themselves, Chronoa steps in to paralyze the enemy so that the character can whale on them.
Space-Time Transfer isn't BFR, it's Summoning - an ally appears from a portal to attack the enemy (or debuff them in the case of people like Super Giant Lord Slug or Zen-Oh) and are then returned to wherever they came from. For the player it requires the Hero Avatar (ie Beat) to be on their team, but that's game mechanics - bosses (such as Demigra in GDM7, or Xeno Janemba in World Mission) are perfectly capable of using it without a Hero Avatar.
I've expressed my disapproval of using CI for abilities in the past, other than that I agree with your list.
