Some interesting choices.
I didn't think Kelly was in and out. He had an injury but regular first choice now isn't he? McGinn's due back much sooner isn't he? McKenna's out as well. As mentioned Cooper will be in and you can't leave Naismith out. He's been dropping back more so Hearts aren't so reliant on his goals. So, I'd go with,
Kelly, Marshall and McLaughlin
Palmer, Jack, Cooper, Gallagher, Hanley, Findlay, Robertson, Taylor
McTominay, Fleck, McGregor, Forrest, Christie, Fraser, Gilmour, Armstrong, McGinn
Griffiths, Naismith, McBurnie
Assuming Tierney and Burke are out. As mentioned elsewhere I'd have Jack as the replacement right back.
