I think they might do it from time to time. They definitely see him as a center but I don't think they're really worried about him developing there too much as his two-way game is already pretty refined and he's shown adaptability moving from C to W last year.
Ideally you would have Dach locked into the 2C slot to give him as much ice time at C as possible, but his development has to be balanced against opportunities for other players and we're kinda short on quality RWs right now. If sticking him on Caufield and Suzuki's wing for 4-6 weeks gives us better options to give Newhook (and maybe Slaf) more ice time, try him out at C, while still getting Dach 18+ minutes with skilled players I don't think they'd be too torn up about it.
