I found the perfect solution - in the DMG (page 175-176). About the Undead Hunter (a variant of the ranger) - Direct quote from the DMG:
"It's possible to create entirely new classes, or rather, to alter existing classes so drastically that they're no longer recognizable. For example, you could make the following adjustments to the ranger.
So I can take 1 level as an Undead Hunter and use my sneak attacks vs undead.
Something that the DMG did not do that I would of is remove Wild Empathy from the ranger list of class skills as well.
What say you Myth: yay or nay?
"It's possible to create entirely new classes, or rather, to alter existing classes so drastically that they're no longer recognizable. For example, you could make the following adjustments to the ranger.
- Limit his weapon selection to resemble the rogue's list of weapon proficiencies.
- Change his favored enemy ability so that it applies only to undead, and his bonus improves by 2 every five levels.
- Give him the rogue's sneak attack ability, but change it so that it's only usable against undead.
- Change his spell list so that it consists of spells that deal strictly with undead or that are used for subterfuge and sneaking.
At 3rd level, give him the paladin's smite evil ability, usable only against undead.
