Double doors. Possible, with some creative use of entity doors and static entities. Essentially you would forgo the use of segment doors which are a fixed design. Go to entities library and find the scenery folder. You will find all the doors, no frames just the doors. Select one and place it on your level, the rotate it 180 degrees and place it again (the telescopic door is best for this, swinging doors get predictably odd results). Now if you placed your door up against the walls you want the door to full, you will have a gap. For this use any static entity to fill up that gap and there are a few to choose from. This way you can cobble together your double door and it will look right in the game. Of course you could hire a professional artist to create an animating door and static door frame and then a sound engineer to create your open and close sound effects. This double door request might cost you (£12x8hrs)+(£12x2hrs)=£120=$200 in the triple A world, but in the land of FPSC where creativity and cobbling rules, all it will cost you is time.
