Ya thats fine. But if you play Ecclesia now, you'll find the the other to possibly under whelming. I'd recommend Dawn of Sorrow, then Order of Ecclesia, then Portrait last. The reasoning is that Dawn of Sorrow is amazing if you didn't know Ecclesia existed, and Portrait last because maybe if it's the last one you play, you might end up skipping it. Or if you do play it, you can join us in bitching about it's less than perfect formula.
