That would pose the same problem, and more.
Not only would it break scripts or require adding an alias,
but converting the command name from a single token to
two tokens would require changing the command-parsing logic.

How about creating a shell function?  E.g., put this in your
.bashrc (change "acheck" to whatever name you like, and change
"opt" to "min" if you'd prefer the latter)

    acheck() { parted -s $1 align-check opt $2; }

then you'd type only things like this at the command line:

    acheck /dev/sdd 1
    acheck /dev/sdd 2
    acheck /dev/sda 1
