Before the two-day US Open mixed doubles, sources told BBC Sport it was unlikely the rest would deviate from the traditional format.
Tennis Australia is equally as bold as its American counterpart and tries to attract new audiences with radical ideas.
It is acknowledged the Melbourne event – which was the first major to bring in 10-point match tie-breaks – is the most likely to attempt something similar.
However, it does not have the same financial clout as the United States Tennis Association, which was able to offer the mountain of prize money and appearance fees upwards of $50,000.
Neither does the French Open, nor Wimbledon.
Also, the two oldest Grand Slam tournaments are generally more reluctant to break from time-honoured traditions.
However, the success of the US Open event – which organisers say attracted 78,000 fans to Flushing Meadows – has led to increased discussion about the future of mixed doubles.
Even though Raducanu and Alcaraz lost in the first round of the 16-team event, it did not dampen the Englishwoman’s enthusiasm about the experience.
“I think it was a huge success,” said Raducanu. “I think so many fans got involved, so many people watching and tuned in. It got a lot of attention.
“It was a great idea and I had a lot of fun on the court playing with Carlos.”
