B-HKT was a bit of a special case - I'm assuming they will completely rip out the new J prototype and refit it properly. It is quite different from the later fit-outs: a lot of the materials were temporary, the power sockets were wrong (didn't take HK/UK plugs - the later ones do), and so on. Moreover the partitions on HKT are a little higher than those on the later ones. I don't think it's "fixable" - I suspect it will simply be redone from scratch.
