It is generally not recommend that you house two snakes together. It can be done, but it brings some complications with it. If you ultimately decide to house them together after everyone here details the complications involved, make sure you quarantine your new snake for at least 60-90 days first. You really want to make sure your new snake is healthy.
Secondly there is no jungle carpet ball python morph. There is however a jungle carpet python which is a completely different species of snakes and I strong recommend that if you decide to work through the complications of housing two snakes together that you make sure they are at least the same species.
Edit: There are also hybrids called Carpball, but that's not a technically a morph.
