Yes, it's a challenge, but not unbeatable. My alt just beat it in 5th attempt with the following starting lineup:
Home One: 5*, 72 ship — 7*, g7, 75 commander
Biggs: 7*, 85 ship — 7*, g11, 85 pilot
Wedge: 7*, 85 ship — 7*, g11, 85 pilot
Ghost: 6*, 80 ship
Phantom: 6*, 80 ship
JC: 7*, 84 ship — 7*, g8, 85 pilot
Replacements:
Ahsoka: 5*, 80 ship — 7*, g8, 80 pilot
Falcon: 5*, 80 ship — 4*, g8, 65 Finn, 7*, g8, 72 Rey
Phoenix pilots are mostly 7* g8—10 with Chopper at 6* and Sabine at 5*
I had previously failed several times with 5* Ghost/Phantom and level 70 Home One.
Keep upgrading your ships and pilots, and you will eventually succeed.
My profile on swgoh.gg didn't update yet. Only difference is a level 72 Home One (now at 6*):
