The Mercedes McQueen actress said she hopes her on-screen sister Hackett will have a second spell on the soap, despite the fact the character Tina Reilly was killed in 2008.
"I'd love Leah Hackett to return. I saw her for dinner recently and really miss working with her," she told Inside Soap.
Praising her former co-star, Metcalfe added: "She's been going to lots of auditions and appeared in Good Cop. I'm proud of her, she's just as great as ever."
Producers brought back Warren Fox (Jamie Lomas) last year after previously killing him off in a nightclub fire.
Meanwhile, Roxanne McKee revealed earlier this year that bosses asked her to reprise her role as Louise Summers, who died in 2008.
