I know it's only a sample size of one, but I have a buddy who bought one original-colorway '22 EZ98 last fall (mid production run), then another in Aqua Night as soon as they came out this past spring, and the Aqua Night variant feels more cumbersome to him. I haven't had a chance to measure the spec on both yet, but needless to say, Yonex's QC is a whole lot more like everyone else's than some here like to convey. So as with almost every other brand, I would say if you go plucking random frames out of completely different serial runs, with different paint jobs no less, I would expect at least a small amount of different swing feel, for sure.
Safest bet for those who are truly anal: if you already have an original-colorway '22 EZ98 and want to duplicate as closely as possible, I would stick to that model and pay for a matching service on your unstrung stock spec. Otherwise, dump the original, and reboot completely on two or more matching Aqua Nights. Just my two cents.
