That is... very complicated and I'm not sure I'm reading it right.  I don't know the reference, but it seems like the goals are to deal 4 radius damage on death, be untargetable by direct fire, and equip two titles (tie shuttle and snaplaunce).  I'd cut out all the intermediate steps and say this on the pilot & title text:

Pilot (PS 2 scum TIE Bomber): "Equip the TIE Shuttle and Vote Snaplaunce title cards, and you cannot equip other title cards.  When you are destroyed, deal 4 damage to each ship at range 1 of you."

Title: "You cannot be declared the target of attacks.  When there are no other friendly ships on the table, discard this card."

I'm still not comfortable with the title.  It's a problem when there's no way to target a ship for attacks, no matter your PS or your abilities, especially if that ship can load points and be somewhat fat.  It allows someone to castle a bunch of points into the untargetable ship so they win more easily and/or with a wider MOV, or lose by a lower margin.  Especially if paired with other hard-to-kill ships, this is very exploitable.  The no targeting (so bombs and other damage abilities are required) and the explosion at the end (if they succeed they risk losing a 50-point ship) make it a raw deal for your opponent.  That's why Captured TIE  works the way it does -- once out-skilled or isolated, you can be targeted, and it's on a very cheap & low-threat ship that cannot even attack while protected.

Also how do you plan to trigger the explosion?  Bomb your own ship with allies?  Again, I don't know the lore so I'm probably missing a lot of the idea.  I'm just focused on gameplay and how I can see it being used.

From what I think I'm seeing, the ship is so focused on one gimmick that I'd recommend instead of doing it as an expansion, just do it as a mission.  Then it becomes interesting and fun as a one-off, and people aren't buying a new expansion of a ship that only does the one thing.  One player builds a fleet around Snaplaunce, who is pre-built a specific way, and the player has 75 points for the rest of their fleet.  The other player has 100 points for a counter-fleet.  Figure out win conditions for each team and possibly other scenario parameters, and you're good to go.

Missions are a great way to do a quirky or thematic ship or scenario like this.

It's not specifically pre built. yes it is a very vauge legends reference. there are two crew slots and four illicits, not necisarily dead man's switch, you could get a lot of fun out of the many different combinations avalible. loadit up with hot shot blasters, give it Munitions failsafe, and put greedo on it. if you were to use the x4 DMS, then just have a friendly ship with R5-TK. there are many possibilities.
