How wide? Do you mean 5 blocks long? How do you want it to move back into the wall? What sort or area are you working with, as I'd need to know that to figure out how best to hide the circuit. If you are asking can we move a single file line of 5 blocks back into the wall in the same way it moved out...then....not exactly. You can only pull one block back at a time. The reason the extenders work is because blocks can push each other. Though, it COULD be possible if you had a clever way to chain pistons to push the blocks back in. It wouldn't LOOK like you might be thinking...but it would function all the same. No, you cant just suck 5 blocks back into a hole. You can pull ONE block. You can push them back in the hole, however. If I'm wrong, then someone could enlighten me and I'd be thankful even.
I just had an amazing idea. You could make a single block deep trench of lava. Then have pistons push out a sand bridge. Then, to remove it, you could have pistons pull out a space under the lava as wide as the bridge, and then shut it off again once the sand fell into it. Then have an underground system move the sand back into default position again.

I would like the bridge to be 2 wide, and it needs to be 5 long. It's purpose is to let people in my world from the immigration center I have set up. As far as the area, the bridge destination would be obsidian and at the bridge starting point anything could be dug. The mechanisms would have to be hidden all on the land side and nothing on the obsidian or in the lava trench around it. I can post a picture of what it looks like.

LMAO - We need to use this idea around our borders!

Heh - And I used to be the one saying "Really? You're playing NerdCraft??"
I've seen some pretty neat things done with pistions, but this is one of those things I don't think it can be done. It may be possible, but very impracticable. The amount of complex redstone would make this a very large system.
The problem isn't the bridge poping out, but getting it to disappear is the problem. Unless you don't mind destroying the bridge by hand each time.
However it's somewhat complex and hard to explain. And ontop of that I'm not sure it it would work with the current idea I have. Normally I'd do something like that in my own world and get back to you, but I have so many other things to be done, sorry.
Edit:
Maybe have sticky pistons push cobblestone out from the bottom of the lava. But that'll require you to change up your current set up and remove the lava before you get to redstoning.
Well I figured it out, but I'll have to mine the blocks away after each use, I'm using two cobblestone generators with a pistons pushing them out, I just need help wiring and connecting everything

There is a double extender setup which can push/pull a block from two blocks away. I use this on my secret door with the dual sticky pistons hidden under the couch in my living room (the couch is 4 stair blocks side by side with signs on the ends for armrests). See this thread for an example, it works perfectly on xbox - look at the fourth post in the thread by Peppe. Very very simple configuration. Since my blocks are floor blocks I had to run power up to the pistons from below and I had to add additional repeaters for a few extra ticks of delay but it works great because speed is not an issue with secret doors.
There is also a triple extender that uses three sticky pistons to push/pull a block THREE blocks distance, but the wiring for that is obviously large and complex. Not something you can fit in a smaller space. Haven't tried that one yet.
P.S. At the beginning of this video is a vertical double extender. I copied it and it works perfectly as well.

I just want it to push a cobble bridge to the obsidian and then retract

You also might need one to push out above the path to split the lava around the door and path. Bigger obsidian pad so the bridge is a jump away
I would do one but my spawn is in, on and around part of my castle
