In 1977 I bought a Gibson EB0, about 10 years old at the time, and rather battered, but played (and still does play) like a dream.
But it lacked the tones I was looking for, so I had a J P/U professionally fitted at the bridge. It gave me all the brightness I could ever wish for, and then some! For the best part of 20 years it was my main instrument, couldn't find anything to touch it in terms of playability.
But now it's in retirement, and if I wanted to sell it on, the authenticity value is gone forever, short of investing in a serious refurbishment.
But for many years that guitar was a big part of my life, and although purists would tell me I wrecked it, my own opinion is that I turned it into a far better musical instrument - which is first and foremost what I wanted.
Regrets? Well OK, a few, sometimes.
Would I do it again? Yes, no question.
