It all depends on what Estelle goes for I think. If she leads with one of her heavy duty spells she can debuff Alucard to hell, damage him and then keep him busy long enough that Joshua can dispatch Link maybe and get something done. If she jumps straight to thwacking Alucard with a stick things don't go so well for her and then it's Josh solo vs Alucard which...might be possible to clinch but I wouldn't bet on it. I feel like starting off with a spell to supplement Joshua's ambush (something like Megalith Fall, which reduces defense guaranteed, or Gravion Hammer which lowers speed and movement range, also guaranteed) is sensible, and it'd make things more even.

The other thing to note is Estelle is naturally built for a tanking setup. Her Master Quartz are Skuld and Brigid, the former of which grants automatic 10% max HP regen at start of battle (and again if she drops low) and tacks a bit of extra further regen on top at all times, and the latter of which automatically maxes out her CP if she dips low. So she's going to be hardy and if she gets put against the ropes, she'll be able to bust out a limit break instantly. Whether that's enough to buy the time she needs to either retreat to heal or let Josh come in to help, I don't know.
