XF 1.5 Replacing Like/Unlike


Is it possible to change Like/Unlike?

Hypothetically- A site for 1970s nostalgia enthusiasts could have "Dig it/Undig it"
All trophies/alerts/etc would be changed also-
"John Doe dug your post..."
"You have been dug X times..."
(sorry, a lame example, lol)
If it is possible, would you please direct me to where I could hire someone to implement the changes?
