I had seen your message to the list related to this idea before [1], so I went back to research what the viewpoints and conclusions were, if any. I didn't find anything too conclusive, but I did find some persuasive points by Dave Hudson [2] [3] [4] [5] that seem to also favor increasing the target block creation rate (decreasing the target time interval between blocks). Considering that increasing the target block creation rate could reduce the effect of (but not solve [6]) the fundamental mismatch between transaction creation and the Poisson process of block discovery [7] and could reduce miner variance (possibly an aid to miner decentralization), I think I'd go with option B to answer your question. I wonder why this does not seem to ever gain more traction when you bring it up? The idea does not seem crazy.
