I like oatmeal, but the old-fashioned kind has a nicer texture- a bit chewy, not like thick wallpaper-paste. Actually I've never tried to eat wallpaper paste so I'm not totally sure about that last... but the instant- or quick-cooking oats are definitely very mushy. My local health food co-op has about 4 different kinds of oats- thick cut and thin, organic or not. The thick-cut oats are a bit chewier and I prefer them, but lately they've been harder to digest I think.
Quick-cooking oats might be less pasty if you try bringing an amount of water equal to the measure of oats you're using to a boil, dumping in the oats, bringing to a boil again, covering the pan, and turning off the heat. (If you're using an electric range you might want to make sure it doesn't boil over after you turn the heat off)
All the things you're planning to add to the oats are great ideas. Cardamom powder is nice too; some people might like ginger.
