So far as i know, on a dual filament 1157 bulb, when one filament is on, the other is off. This may not be true in all applications, but that is the way they work when used as signals on my Honda. I cant recall if the lower watt filament stays on in the back brake light application.
So, to answer your question....you want to "hot up" both the 8 watt filament and the 27 watt filament at the same time, all the time, yes? Seems like a waste of power. The 1156 and 1157's cost virtually the same, so I would just hook up the brighter filament an cut the other wire off and tuck it. Electrically speaking, no...there is no reason you cant do that...but they will draw a max of 35 watts each (yikes) and you may burn the lenses. These are not huge light assemblies, and the bulb takes up much of the interior room.
I can post a pick of one sitting next to say.....a quarter and a pack of smokes so you can see what you are dealing with in size.
As I said...I switched out the original bulbs for LED's and have no heat worries.
