Lewis's had attracted the backing of the SEED Foundation who had previously backed Marina Erakovic and Sascha Jones but that support ended after she played a series of ITF tournaments in Egypt in February.
Rea thinks Lewis showed enough in her appearances at the ASB Classic to suggest she can make it as a pro should she choose to resume her pro career at some stage.
"It's uncanny when you look around the tennis world how often players will return from a break that is intended to be a permanent break and it often becomes a temporary break so I wouldn't be surprised to see Jade return to the courts in due course, and hope that's the case," Rea said.
Meanwhile in other tennis news Kiwi Michael Venus and his South African partner Raven Klaasen are through to the quarter finals at the Monte Carlo Masters without getting on court for their second round match.
Fifth seeds US Open champions Jean-Julien Rojer and Horia Tecau pulled out of their second round encounter through injury handing Venus and Klaasen a walkover win.
Venus and Klaasen will face Italian wildcards Fabio Fognini and Simone Bolelli for a place in the semi-finals tonight at 9pm NZT.
