A mixed team version of the Battle of the Brits will take place at the end of July, with Andy Murray and Johanna Konta expected to take part.
Jamie Murray, who organised a men's version in June, and the LTA will stage it at the National Tennis Centre in London from 27 July to 2 August.
Two teams of 12 - selected by non-playing captains - will chase points in singles, doubles and mixed doubles.
Murray is confident his brother, Andy, and world number 14 Konta will be involved.
"I cannot tell you with a gun to my head that they will be there, but they both said they like the idea and intend to play as long as fitness is there," said the Scot.
