Rogues could work as hybrid. They have access to 2 magic armor braking skills (Gag Order and Chloroform) scaling with finesse
Fighters classes could also work as hybrid since flay skin and medusa head scales with str.
Summoners could work as hybrid as they could switch summons/infusions based on encounters. All summons scale with summoning skills so there are no penalties.
Mages? Nope. You can't learn corrosive touch until the final chapter.
Sure, rogues have access to a few magic armor reducing skills, but unless you are running 3 mages, would you rather not use something else? Also, Gag Order is an unfathomable 3 AP, but doesn't do close to 3x the damage of Chloroform.
