Scott Pye is set to join Mark Winterbottom in an expanded Team 18 line-up for the 2020 Supercars season.
The Charlie Schwerkolt-owned squad will move to two cars next year, the expansion underpinned by one of two Racing Entitlements Contracts put on the market by Kelly Racing.
The 29-year-old is currently off-contract, 2019 the final season of his three-year deal with Walkinshaw Andretti United.
Pye currently sits 14th in the standings, three spots behind Courtney and seven spots back from where he finished the 2018 season.
His stint so far with WAU has yielded a stunning win at Albert Park last year, and a pair of seconds at the Bathurst 1000 (2017 and 2018).
Should Pye's Team 18 deal go ahead, WAU will sport an entirely new driver line-up in 2020.
Slade, however, is being very closely linked to a Matt Stone Racing move, while Brown is considered a big chance to wind up in Sydney alongside Courtney.
