We've been exchanging email ever since last night's session zero.
We got some clarification on what she meant by "adventure path with modifications." She's going to be running Princes of the Apocalypse, with parts of Rime of the Frost Maiden and other side-quests added in as well. (That bit about how we all met and learned to work together, the tavern being destroyed by a storm? Yeah, that was foreshadowing.) She wanted to pad the material out a bit so that it would take us to almost 20th level. So when she said "with modifications," she meant that certain pieces of the story would be expanded and others might be shuffled around...not that she would be tailoring the AP to our characters or party composition. "I plan to run things as-written, just in a different order."
Folks here might get a chuckle out of this, too. One of the players asked, "are you going to put extra magic items in the game for us, since we don't have any spellcasters?" Her reply: "We've been playing together for years, you don't need me to hold your hand."
She kind of has a point. She did her part at Session Zero: she told us the rules we would be playing, the resources that would be available to us, and the campaign setting we would be adventuring in. We took that information, understood it, and then (perhaps unwisely) decided to roll up a party of characters that doesn't cast spells. We chose a difficult path, but that was our choice to make and she's here for it.
