Terminal: map super/command key in stty

Question

I want to remap terminal shortcuts (In particular, I want to remap INTR from CTRL+C to Command+C) in Terminal.

So these are my current stty bindings

$ stty -a
speed 38400 baud; 38 rows; 179 columns;
lflags: icanon isig iexten echo echoe echok echoke -echonl echoctl
    -echoprt -altwerase -noflsh -tostop -flusho pendin -nokerninfo
    -extproc
iflags: -istrip icrnl -inlcr -igncr ixon -ixoff ixany imaxbel iutf8
    -ignbrk brkint -inpck -ignpar -parmrk
oflags: opost onlcr -oxtabs -onocr -onlret
cflags: cread cs8 -parenb -parodd hupcl -clocal -cstopb -crtscts -dsrflow
    -dtrflow -mdmbuf
cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>;
    eol2 = <undef>; erase = ^?; intr = ^C; kill = ^U; lnext = ^V;
    min = 1; quit = ^\; reprint = ^R; start = ^Q; status = ^T;
    stop = ^S; susp = ^Z; time = 0; werase = ^W;

And for example if you want to remap something it'd be like

stty intr \^c

Which maps SIGINT to CTRL+C

But I want to map SIGINT to COMMAND+C. Something like this (which is invalid):

stty intr ⌘c

Now I know that the terminal doesn't really recognize the Command key, but is there a creative way of doing it?

Note: I know it can be done with ITerm2 but am wondering if there's a way to do it with the vanilla Terminal.

Thanks

@Niklas I solved the problem, but not using stty. Instead, I've been using Karabiner-Elements to do custom configuration on the Terminal keys (without affecting the rest of my bindings).

Basically you install the Karabiner-Elements app and then write a "complex modifications" rule in the karabiner.json file to swap whatever you want. Here is a guide on how to configure the json config.

My karabiner.json looks something like this:

{
  "name" : "com.apple.Terminal",
  "simple_modifications" : {
    "left_option" : "left_control",
    "left_command" : "left_option",
    "right_control" : "right_command",
    "right_option" : "right_control",
    "right_command" : "right_option",
    "left_control" : "left_command"
  },
  "complex_modifications" : {
    "rules" : [
      {
        "manipulators" : [
          {
            "to" : [
              {
                "key_code" : "c",
                "modifiers" : [
                  "left_command"
                ]
              }
            ],
            "type" : "basic",
            "from" : {
              "key_code" : "c",
              "modifiers" : {
                "mandatory" : [
                  "left_control"
                ],
                "optional" : [
                  "any"
                ]
              }
           }
        ]
      },
      ... more rules for all the stty characters, etc
    ]
  }
}

For only iTerm2 users

You just need to add a key binding in Preferences. Preferences -> Keys -> Key Bindings. Add a new keybinding, choose your keyboard shortcut and choose action as Send Hex Code. For example I configured ⌘Y to Ctl-C (interrupt).

Follow this link to find hex codes for Ascii control codes (control characters, C0 controls).
