That is easier said than done when you take a look at the players who will be missing from the GUINNESS PRO12 outfit - Iain Henderson, Darren Cave, Dan Tuohy, Peter Nelson, Jared Payne and Tommy Bowe.
But Kiss is only concerned with the opposition, one he knows is packed full of talent whichever starting XV they opt for.
"One of the worries is we don't know what team they're going to pick," Kiss told the Irish Times.
"When you look at the back row - [Imanol] Harinordoquy, [Louis] Picamoles and Tala Grey - that seems obvious but they've got other options around the edges in that position. [In the] back three [behind the scrum], there's options there too.
"Will they back themselves from anywhere on the pitch which they do a lot? Yet there are other games when they kick.
"They're merging their game into an adaptive beast. I think that unpredictability, from selection to style, is a real danger."
