Combo widget changes in child theme?

I modify the code in enfold/framework/php/widgets/widget-classes/class-avia-combo.php and enfold/framework/php/widgets/widget-classes/class-avia-combo.php to change the appearance of the Combo Widget.

At present I alter the files in the enfold directory, which means I have to re-do the changes on every Enfold update, even if those files don’t alter, then re-upload the files with my mods in.

Is there a way to have my modified files stored and loaded via my child theme, in a similar way that I do this for iconbox: enfold-child/shortcodes/iconbox.php?

(I know that if there are changes to the widget-classes files that I’d have to re-do my mods but at least if there’s a way via the child theme I wouldn’t have to re-do the alterations on every Enfold update.)

Or is there another way to do this?
