There is the 500TB asset server full of jpeg2k images. Switching to a
new format would be a massive undertaking.

TGA is uncompressed so it won't work. PNG could work, but its
compression ratio and file overhead isn't that much better than
jpeg2k. So the gains would only be in decode time, which is the
biggest cpu drain in the viewer so it may be worth it.
