Happytealmazda has proven that a B2600i tranny will bolt up to a 2.2 block. Jim is in the process of starting a turbo 4x4 truck build, similar to his teal turbo truck but this one will be a B2600i 4x4 with a 2.2 turbo engine.
The hardest part though will be the engine mounts, wiring, exhaust mods, etc.
It can be done but it will take some work.
But yes, the easiest way would be to find another 2.6 G6 engine.
