Over-under-over/over-over-under(3X wheel lacing)

indeed. - actually it looks quite nice

It looks nice indeed and is called interlacing - congratulations. Straight from the textbook as well (Jobst Brandt):

Interlaced spokes permit opposing spokes to take up slack from each other during severe wheel loading and prevent them from completely losing tension. This prevents the nipples from unscrewing. The pressure interlaced spokes exert against each other allows a loaded spoke to return to its original tension with less shock.
I rode an interlaced rear wheel for two or three years on the road and found it was bouncy and comfortable and didn't come out of true at all. After said 2-3 years the spokes started breaking at the first bend/crossing where they sort of hug each other (where you've gone over instead of under). Replaced the spokes without interlacing, because it would've been such a pain trying to feed them through the fully tensioned wheel. All good again.

If you haven't undone the pattern, I'd just go with it. In truing and tensioning I found that I needed to treat the interlaced spokes as one, because they seemed to tension together, if that makes sense. Change in one would immediately have an effect on the other.
