LIGO detects the changes in distance between mirrors down to 1/10000th of a proton 1 atto-light-second is a few hydrogen atoms long. So still seems like quite a few orders of magnitude needed for gravity wave detection but perhaps with the lengths involved? Some more expertise is needed. I would guess probably not but also not so far off as to be crazy.
