Burning unburnt gas in the exhaust is already taken care of. It is called your EGR: Exhaust Gas Recirculation. It recirculates exhaust back into your intake to burn the unburnt gas to save a few miles per gallon. Thats what you were thinking of.
FYI: Its also one of the reasons our intake manifolds get so damn dirty.
No it is not.
The reason the manifolds get so dirty is they injest oil from the valve cover vents and PCV system.
Mainly from the vents (at rpm levels above 5k) though as the 2.5L does not drain the heads effectively and raw oil gets sucked into the vents and directly into the intake.
There is no cure for that problem except running a Full 3L engine since it has extra, larger drains to solve that problem and the high rpm oil starvation one as well.
The PCV problem can be curtailed by running a PCV seperator.
Actually, it can be solved completely by plugging the left head and right head hookup in the goose neck and reroute all 3 lines to the seperator and then run the seperator "out" line into the PCV nipple below the throttle body. Granted, it will have to be drained at least once a month if no sooner, but at least you will know how much oil you are now NOT burning and running through the UIM/LIM assymbly.
Hmmm, ok cool, i have been burning a lot of oil, a lot of highway driving I have been doing, so I might just do that. Thx!

How would unburnt fuel vapor get burned up in the exhaust system?
Ohhh Ohhh, I know! 
In the catalytic converters if you still have 'em. Otherwise it won't get burnt up, or more accurately converted.
And in no way does it actually help.
