Quite possibly that's why there are no mods as you suggest. The full three words for Fus Ro Dah are certainly a lot more powerful than just the first word.
That Thu'ummic sounds like fun, but I'd have to remember the actual words! No chance!
Actually, so do I! Fus Ro Dah can be a life-saver to blow enemies away when you need to scoff some healing potions and run away. I've never "shouted him apart - with my voice", though. Hot-keyed potions can be a life-saver as well. But with flying Dragons I often miss completely.
Actually, with CFM you could hot-key 8 shouts. You just need to remember which number is which, Then there is the cool-down time, anyway, so you cannot rapid-fire them like with spells. So I use a Shout, select another...
But I never go into battle with Whirlwind Sprint selected. I use it when needed, but then revert to something else.
Well, some higher level poisons are better then no poisons at all, but to get the best out of your own you need to get Alchemy V and all the other perks that increase poison damage and gives you the double dose effect. Plus, with maximum Fortify Alchemy equipment (enchanted with maximised Fortify Enchanting potions), they can be quite astonishing. With Dragonborn, you can harvest Scathecraw on Solstheim, which lets you brew potions of Damage Health, Lingering Damage Health and Ravage Health when combined with Imp Stool and Skeever Tail. Devastating!
Unless the enemy is immune to poisons.

Actually, I have an Alchemy mod which balances Herbalism by splitting into Healer and Poisoner branches and makes Green Thumbs available to both. And all the ready-made poisons and potions are more powerful and those you brew will match more sensibly. It is not released as I have more work to do on it and I am too busy with real-life until after Christmas. I wanted to enable NPCs and other enemies to use the same poisons against the player as well, so it was balanced. And you can brew Cure Poison with it, which works well with Realistic Poisons by WarriorWithin83, which makes all the venomous creatures much more deadly.
