How hard would it be to implement an emoji reaction system (like Telegram) instead of Up or Downvotes?

I recently read a funny comment and wanted to give it the 😂 reaction like I would on a Telegram post, but upvoted instead. Reddit had upvoting downvoting but wondering if Lemmy, being an open source innovative software, should evolve past the upvote downvote and allow for a wide range of emoji reactions to a post.
