If you aren't worried about accuracy, sure, that would do the trick.
Separate transistors will never be as good as a dual, due to the thermal lag
caused by the separation of the transistor dies in their own little epoxy
packages.

>Also, how do you "join" the 2 transistors together ?

A wire tie around them, with them flat to flat will do the trick. Some
people go as far as epoxying them together.
