I think what you are describing is a little too powerful. Whips aren't all that bad as they are really - my first character used one, although his reasons were because I was adding a little more realism to the game. I decided that while mounted on a large creature, I would need a reach weapon o be able to target small or smaller creatures on the ground, so a whip was necessary (that isn't actually a rule, it is just logical). Still, the whip's extra reach was more than enough to compensate for the slightly reduced damage and the damage really is only slightly reduced - never think otherwise. With Duelist and a +5 ability modifier, you are looking at only of an average 1.5 damage deficit per attack against AC 18, compared to the Rapier. That isn't enough to be concerned about and it certainly isn't enough to warrant a free supercharged trip rider.
If you feel the need to offer more compensation for that 1.5 damage other than just the extra reach, then just make that reach count for more. Given them the ability to grapple and trip people with the extra range rather than just 5'. If that isn't enough, allow them to do so with Dexterity (Athletics) checks when using a whip, or even Dexterity (Acrobatics) checks if that still makes sense to you.
