A junction between multiple wires has to be designed to take the number and size of wires used, each join provides a resistive junction, resistance + amps = heat. The box also has to have space for the wires.
Absolutely not. No splicing in a conduit body. They are only to help fish wires. Now -- there is an utterly useless exception. If the conduit body is stamped with a number of cubic inches, then you can apply the junction box fill rules instead. In any size of conduit that's reasonable for your wires, there aren't nearly enough cubic inches in the conduit bodies! If you look very closely inside the box, it should indicate the cubic inches of the box. Please provide this number and we can tell you the number of conductors that can be placed in there. Please note that there are additional considerations, like whether the box itself will have a receptacle in it (a receptacle typically counts as 2 conductors).
