Minor thread-necromancy, as I just found this via SmiloDan's class thread. Here's a spell-less Bard variant I put together several months ago and shared at ENWorld. It's a Sendspace link and is a little heavy on the sketchy ads, so sorry about that. Just click the "click here to start download from Sendspace" link, not the duplicitous "Download!" button ads. Anyway, let me know what you all think.
Also on topic, the Warrior of Holy Light and Skirmisher are APG archetypes that are great spell-less paladins and rangers, respectively. Here are some good 3rd party sources for other spell-less variants:
The Expanded Spell-less Ranger (Open Design: Expansion of the class featured in Kobold Quarterly 11)
Alchemists' Discoveries (Super Genius Games: can swap extracts for one of two nifty alternate abilities)
Inquisitor's Judgements (SGG: features the Justicar variant class as a spell-less Inquisitor)
