In all honesty I think Hybrids are mostly fine depending on what you are trying to do. A common strategy is just to get the bare minimum attribute required to use their skill with a 100% success rate and then basically ignore it for the rest of the game.
Yet if you try to go 50/50 and make both skills viable at once usually you end up starved for AP, HP, and don't perform as well... unless you know every single secret in the game or are playing as a Lonewolf.
So the hope of this brainstorming thread is to try to find ways to make these hybrids better
-Physical + Magical
-Marshal + Scoundrel/Ranger
So far I only have two ideas.

1) Quick Swap Talent: With this talent you can either swap weapons at the start of a turn for free or alternatively it could allow you to swap it at anytime during your turn for free but once. Allowing you to switch from knives to bows or from two handed axes to staves for example.
-Requirement: Two points in two separate physical skills.
2) Swords/Knives/Axes that Serve as staffs and wands: I like to call these Foci Weapons but the basic concept is that these uncommon weapons can be used to physically attack and do the ranged magic attack. As well when randomized they can have bonuses from both the mage and Rogue/Warrior pool. So one that increases intelligence and Dexterity would be possible.
