Wales make three changes to the starting line-up, with Amy Day coming in at scrum-half while Mared Evans and Ceri Redman take over at full-back and centre respectively.
And Lewis insists a top-two finish is by no means out of their grasp – as long as they manage victory over Ireland.
He said: "We've set ourselves a really tough challenge. The bottom line is we have to go to Ireland on a Friday, play under floodlights, on the back of a loss and we have got to get a win.
"But it's going to be tough, very tough. Ireland always targets us as a side to knock over as they see us as a side immediately above them in the pecking order.
"The Six Nations is still wide open. If we beat Ireland and Italy we could still finish second. In our minds it's everything to play for.
“We've got to go to Ireland confident we can start to see some of our potential come through which we began to see against Scotland.”
