Assuming you will be using Hera the Ghost is 40 points base. Let say you add lando and another 3 point crew, up to 46, then a system, 3 pts. 49. Add exp interface 3 pts. = 52. And then a turret, lets assume you either use TLT or the one that comes with it, so about 6 points, brings it up to 58. Now lets obviously say we'll be going with a 17-20 point phantom that is naked, for this lets assume 18. up to 76 pts. If you put in a fully loaded no prockets Jake. You would be 4 points over 100. If you were to drop Hera to lets say Chopper, it is possible he is 4 points less than Hera you could fit a fully loaded Ghost with a naked Phantom and Jake in the A-Wing. I feel like that is pretty nasty. Just keep the phantom docked until the ghost is about to go boom and you essentially have a 2 ship list with a deployable 3rd ship.
You're one point short. You want Engine Upgrade instead. Trust me.
Thats fine, there is plenty of options to drop one point there. You could go Recon Spec/Jan Ors instead. Maybe the turret is 5 points not 6. Or you just use an Ion Cannon turret. Maybe the Phantom is 17 points not 18. Maybe you use FCS not another 3 point System. I still think you could easily do it.
Either 17 or 18 is a little on the low side. It's essentially a HWK (with what is probably a better dial) that trades a hit point for 2 Attack. A point of attack seems to be valued at around 5 points or so. If a PS2 HWK is coming in at 16 I'd expect the cheapest Phantom to come in at 20 points minimum and maybe slightly higher. I'm guessing that the cost of the Assault Shuttle is going to be around the cost of an X-Wing with the shuttle maybe being about a point or two less for similar PS.
