It can be done, but you probably won't like the solution. There are
only two command line options that seem relevant here:

* -c <command>, which runs <command> after loading the first file
* --cmd <command>, which runs <command> before loading any vimrc file

The first version has no effect on the second file. The second is
run too early:

vim --cmd 'set nu wrap' -d file1 file2

will set numbers, but wrap will get overridden by -d. And there is no
command that gets run after loading each file, or after loading all
files.

Thus the trick is to start diff mode after loading the files, like
this:

vim -c 'diffsplit file2 | set nu wrap | winc l | set nu wrap' file1

Or if you prefer to have the file names at the end:

vim -c 'exec "diffsplit " . argv(1) | set nu wrap | winc l | set nu wrap' file1 file2
