I don't think this has ever been done before. So suppose the maiden voyage is uneventful, and the Titanic becomes just another liner plying the North Atlantic? And for 2 years, all goes well, then in April 1914 has a fatal encounter with an iceberg, while making a westbound journey in the same location as in OTL? Some obvious butterflies; there are a different set of passengers onboard than in OTL. Also, Edward Smith is no longer captain, having retired in 1912. The ship still doesn't have enough lifeboats, but can the crew, having more time to adjust themselves to the ship, do a better job of filling the lifeboats, so that 1100+ are saved, instead of 700+. Can the butterflies make any appreciable difference to the start of WW 1? Suppose Archduke Franz Ferdinand is somehow on board, perhaps headed for a holiday in America? Or Gavro Princip decides to emigrate, and is a passenger in steerage.
On a personal note, I had a relative who was in New York in April 1912, and she had bought a ticket for the return trip on the Titanic, back to the UK. Needless to say, the White Star line gave her a refund, and she went on a different ship.
