One-handed + Two-handed > Blade + Blunt
Agreed. I think this is the best way to do this because it ties the perks with combat style: a big, two-handed weapon, or a one-handed weapon that can be quickly paired with a shield, spell, or different weapon. Trying to do something else would require too many perks especially since anyone with a one-handed weapon is likely to be switching what's in their hands all the time. Anyway, I think the 18 skills are still going in the direction I predicted http://www.gamesas.com/index.php?/topic/1158511-pollskyrim-18-total-skills/page__view__findpost__p__16993934.
