If Jupiter were to absorb all other planets in the solar system, would it reach degeneracy pressure?
No, hydrogen burning doesn't start until 82 $m_{\rm Jup}$ and deuterium burning starts at 13 $m_{\rm Jup}$, so evidently 1.4 $m_{\rm Jup}$ is not enough for this experiment. 

Your misconception is that


  Jupiter's mass is about the maximum a planet can be before it starts to fuse hydrogen in its core and undergo a massive transformation. 


which is simply not true.
