The actress, who plays Peter's twin sister Lucy, explained that she would be keen to work alongside Law if show bosses decided to bring back his character.
Asked who she would cast to play Peter in the future, Bywater told Inside Soap: "I'd like Thomas Law to come back to EastEnders. I haven't met him, but I've heard he's very nice.
"I thought his portrayal of Peter was really good when I used to watch the show with him in it."
Law played Peter from 2006 until late 2010, when the character bowed out from Walford.
Bywater, meanwhile, has been on screen as Lucy since the beginning of the year - taking over from Melissa Suffield in the role.
