Honestly, stripping out the spellcasting from dragons isn't all that bad. For one thing, the dragons under CR 10 have almost no spellcasting abilities anyway, so, you can ignore it for the most part. I find, for the bigger dragons, simply using a larger dragon without the caster levels works well enough. In other words, if you want to use a CR 15 dragon, pick a CR 17 dragon, strip out the spellcasting and use that.
You get a nice engine of destruction that is a breeze to use.
