Frontpage portfolio thumbnail size (320×240 instead of 500×280)

Hi! I’ve an issue with Corporate Plus Pro theme!
On the frontpage at portfolio widget it uses 320×240 low-res photos. It looks ugly on hi-res screens (width 1366+). I’ve made fix inside template:

acme-portfolio.php line 279:
$image_url = wp_get_attachment_image_src( get_post_thumbnail_id(), ‘post-thumbnail’ );
changed to:
$image_url = wp_get_attachment_image_src( get_post_thumbnail_id(), ‘thumbnail’ );
Now it looks nice, it uses correct 500×280 thumb as described in official tutorial.
I’d like to conserve this fix for next theme updates.
Any advices?

p.s. wordpress v.4.5.3, Acme Fix image applied
