Possible to assign variable as a map?

Is there any way with the filter hook ‘wp_scss_variables’ to assign a Sass Map?

For example:

$variables['palette'] = array(
        'primary' => '#012345',
        'secondary' => '#543210',
        'success' => '#3adb76',
        'warning' => '#ffae00',
        'alert' => '#cc4b37',
    );

This doesn’t work but it seems like there should be some way? Thanks for any help.
