General idea of what I'd imagine Wendy to be like with skilltrees added

I think Vex thing is stupid personally. It's a compensation for the damage she lacks.

I believe that Wendy should summon horde of ghosts at her help with a cooldown involved, like a big supply of damage to help her and Abigail as he would be closer to a minion master herself kinda like Maxwell but with the undead, or those times you summon an army of clockworks into helping you in battle against something.

Ghosts should haunt creatures that are generally could be considered weak like pigs, bunnies, spiders to let you have them become your followers with slightly boosted stats to speed and damage. Maybe have some ghosts have chance to make them become your werepig followers.

Since the idea of making Wendy into a 'glass canon' was the train of thought, what about bringing back the flower shroud and combining it with the wreath you could get the power of having damage redirected and taken by a nearby ghost follower? Empower their movement speeds, attack with them haunting enemies in masses, give them shields to sustain against more than one damaging attack.

She's giving the kind of character who really shouldn't do anything herself like Maxwell. While her gathering speed is not the same as his what she herself would have is Willow's level of damage pressure and protection that getting near her at full power would be really really hard.

In Shadow skill tree for ghosts her followers could become shadow tenticles with red stripes or tip for planar damage and moon one she'll have gestalts doing rapid fires at enemies, not as much as Abigail's damage but they'll make up for it in numbers with the assist of Abigail.

In a way she'll be closer to Wurt as a non DLC character, but having minions she can summons when they've rested enough.

You inspired me, I thought of Void Masque.

I think Shadow Line can have a skill of capture bunnyman,pigman,merm like Void Masque,  every captured mob will make your max hp or max sanity lower. Getting your own undead army.
