When you replace a character via Vehicle, can you choose a replacement character that has hit points less than or equal to the damage that is on the original character? Obviously, the new character would then be immediately defeated, but is that a legal selection?

Now we just need to see someone win a tournament by making Grievous leap off of his bike to his death.

but your opponent still wins if they eliminate your entire squad.

But do Seps really have access to either of those? There are only 2 pieces with Impulsive Shot, 1 is a Luke, there other is a piece you would be killing to trigger in Grievous, Kaleesh Warlord

I'm thinking of a scenario where Grievous gallops at the end of a round and then gallops home to relative safety at the beginning of the next round. In his two gallops he takes out 25 points worth, for example, and damages a bunch of the rest of the squad. He's not absolutely safe, though. The opponent reaches him and takes him down to 20 hit points remaining. At the beginning of the next round, Grievous does a 3rd gallop and takes out another 25 points worth of enemies. Then, knowing that he won't last until his next turn, he drops down to Kaleesh Warlord. The opponent kills Kaleesh Warlord for 22 points. (This sort of scenario is probably most feasible if the opponent has several 15-30 point pieces with 60-90 hit points. Far less likely if the opponent has a huge 70 point beatstick.)

Score so far: Grievous' team 50, Opponent 22.

The rest of the skirmish plays pretty evenly, but the opponent does better. Grievous' team kills another 80 points worth of enemies. The opponent kills another 100 points. Grievous' team gains 5 rounds of gambit. The opponent gains 8 rounds of gambit. Then time is called.

Left on the board:
Grievous' team has 37 points worth of characters remaining on the board.
Opponent has 70 points worth of characters remaining on the board.

Final score: Grievous' team 165, Opponent 162. Despite having 3 more rounds of gambit and having almost double the strength left on the board, the opponent still loses.

That seems unlikely based on the ruling that Sithborg made earlier. Then again, the glossary and FAQ aren't published yet, so I guess it's possible. You could maybe have a glossary entry like this:

Vehicle: At the end of this character's turn, you may replace this character with a Medium character of equal or lesser cost who counts as the given persona. The replacement character starts with damage equal to the damage currently on this character and is considered activated this round. When the replacement character would be defeated, it is not defeated but remove it from play. This character is defeated in its place.

But there might issues with that definition that conflict with Unique or something else. Anyway - we'll have to wait and see what the glossary/FAQ say.

Vehicle: At the end of this character's turn, you may replace this character with another Medium or smaller character who counts as the same character. Remove this character from the game board and place the new character in a space this character occupied. This new character is activated. Place damage on the new character equal to the damage that was on this character. You cannot choose a character to replace the this character if the damage on this would defeat the new character.

Well that part of the glossary text does prevent some of the above scenarios.

I like the extra sentence.

Its a solution only if Grievous Tseu 6 ends up not being competitive. If he can be competitive then its still a problem.
