Replace the smilies with the original versions from previous versions of WordPress.
Added bonus: Disables all “emoji” functionality in WordPress 4.2 and above.

Classic Smilies

I have been using this plugin and I proudly recommend to everyone.
PRO
- It improve performance by removing inline JS and reducing HTTP requests.
Cons
- Smiley images shouldn't be look dull. It could be appear clear like Original.

Thanks & Regards,
