Implement rgba to colorpicker

Default wordpress color picker do not support alpha channel. To turn it on in SiteBuilder I use:

1. wp-color-picker-alpha plugin (https://github.com/23r9i0/wp-color-picker-alpha)
2. and dirty Siteorigin Panels core hack:

/plugins/siteorigin-panels/inc/styles.php

line 183: add data-alpha=”true” attr

<input type="text" name="” value=”” class=”so-wp-color-field” data-alpha=”true” />

line 332: HEX/RGBA/HSLA validation

if ( preg_match(‘/(#(?:[0-9a-f]{2}){2,4}|#[0-9a-f]{3}|(?:rgba?|hsla?)((?:d+%?(?:deg|rad|grad|turn)?(?:,|s)+){2,3}[s/]*[d.]+%?))/i’, $color ) ) $return[$k] = $color;

Is this possible without plugin core hack? Or maybe you can implement this in future plugin releases?

Thank you!
