Not all brown dwarfs have an atmosphere similar to Jupiter, and many brown dwarfs have a much lower temperature than Jupiter.

That means that, like Jupiter, they reflect sunlight in the visible spectrum.
They do not, brown dwarfs are too cool to emit any light, and most can't be seen with regular telescopes, not even Hubble, that's why they can mostly be found in infrared spectrum.
There is even a theory that brown dwarfs could be the missing matter of the universe, and we just haven't been able to detect most of them.
The motion of the stars and galaxies are influenced by material which has not yet been detected. Much of this invisible dark matter, which astronomers call "missing mass", could be made up of brown dwarfs - objects whose mass is between twice that of Jupiter and the lower mass limit for nuclear reactions (0.08 times the mass of our sun).

Granted, a companion brown dwarf is much more distant than Jupiter, but it would form a faint image on any photograph with a long enough exposure.
It would not, thats why they are looking in the infrared spetrum, and astronomers will need about 2 years or more to investigate the images taken by WISE.

There have been many complete sky surveys over the past few decades. If you compare them all, you would be able to discover such a planet by its conspicuous secular parallax.
First of all, and again, such a brown dwarf would not appear in the visible spectrum.
Second of all, and again, just because it hasn't been found it does not refute the fact that there is ample evidence that says it exists.
Do you understand what an "unknown gravitational field in our Solar System" means?

When you do this, you will have actual evidence and I will personally petition NASA to task Hubble to confirm the discovery.
Ah, so you have personal control over the tasks that NASA gives to the Hubble telescope?...
Not to mention AGAIN, that you need an infrared telescope like WISE to even TRY to find such a body.
Not to mention, AGAIN, that the core of at least some brown dwarfs can be as cold, or warm, as the human body, which makes these even harder to find.
I have also presented evidence, many times over, that the Solar System has been getting an exponential increase in interstellar dust, from an outside source of course which is most probably the interstellar cloud which the Solar System is approaching/entering.
ESA sees stardust storms heading for Solar System
PRESS RELEASE
Date Released: Monday, August 18, 2003
Source: Artemis Society
Until ten years ago, most astronomers did not believe stardust could enter our Solar System. Then ESA's Ulysses spaceprobe discovered minute stardust particles leaking through the Sun's magnetic shield, into the realm of Earth and the other planets. Now, the same spaceprobe has shown that a flood of dusty particles is heading our way.
...........
What is surprising in this new Ulysses discovery is that the amount of stardust has continued to increase even after the solar activity calmed down and the magnetic field resumed its ordered shape in 2001.
Scientists believe that this is due to the way in which the polarity changed during solar maximum. Instead of reversing completely, flipping north to south, the Sun's magnetic poles have only rotated at halfway and are now more or less lying sideways along the Sun's equator. This weaker configuration of the magnetic shield is letting in two to three times more stardust than at the end of the 1990s. Moreover, this influx could increase by as much as ten times until the end of the current solar cycle in 2012.

Until you do that, all you are doing is making excuses for why you have no actual proof of your hypothesis. I am perfectly open to the possibility that such a body exists, it is you who have closed your mind to the possibility that it doesn't.
What you call excuses scientists call investigation and research. Maybe you should try it sometimes...
