Well, yes it is possible, but like any game that is more complex than a simple puzzle or arcade game, it will take some work. But technically, you already have everything you need: the most complexe part would be pathfinding and line of sight and those are already implemented in Construct (granted, line of sight in the perspective view of commando might be a bit trickier than a simple top view line of sight)
But, yeah, you won't do it in 5 minutes, but it can be done with some work
