Yep, you could make something like that. There have been a couple Wolfenstein type games/demos made with Construct, and to get that "in the air" perspective like in the video you would pretty much just need to change the angle at which the "camera" is facing.
Here's David's Wolfenstein engine: viewtopic.php?f=16&t=1832
If you tinker around with it I'm sure you will be able to come up with something that will fit your needs.
