There's no problem about which file is input and which output with cp or 
mv, so why on earth would it be a problem with a sane version of dd?

If you really need a hand holding indication of which file is which,

	dd -i $infile -o $outfile

would be in the Unix spirit, unlike the existing form. And with an 
interactive shell you could use filename completion which fails with the 
existing dd.
