Detect reverse bytes?

[hedgehogform]

I found some firmware that requires you to do the command:

objcopy -I binary -O binary --reverse-bytes=4 cloudipcamera_mxic25l12835f.BIN cloudipcamera_mxic25l12835f.BIN.swapped

from this article

Would be cool if binwalk could detect this kind of thing.

First one is scrambled one. the 2nd is the swapped one.
