Unless you loose at least two night of sleep tossing and turning over the angst of this insignificant faux pas I'd just leave it. Especially if it's all trued and tensioned. If it isn't tensioned and trued and you don't like the black bags under your eyes from lost sleep then what the 'ell..... Take one nipple off then a second. Then walk all the spokes around one at a time finishing with the first loosened spoke to put the stem hole in one of the parallels.
