Red splash would definitely be doable mana-wise, but is there a real need for it outside of REB? Ancient Grudge is good against artifact heavy builds, but in my experience Krosan Grip is just as powerful against the relevant artifacts we will encounter, while still dealing with problem Enchantments. Grudge beats Affinity and is cheaper, but beyond that I'm not sure it's super necessary.
REB would be sweet, and I've heard of people doing it before in off color decks. But the problem is many of the decks you want it against will have the ability to Waste you off your red source. RUG and U/W Blade both run Wastelands, as does Fish. Moxes and/or Birds can help, but it's still a bit of a stretch. Having dead REBs in hand seems much worse than being able to drop a Choke.
sdematt, what's your main motivation for the red splash? Maybe we can brainstorm some ideas to really deal with your issues while staying on color.
