DM3, from what i know theoretically, its quite hard to bring evo x engine mods to the current 4b10/11 engine (inspira or lancer) because of the following points:
1. the evo x engine is fine tuned to its spec that its turbocharged and intercooled
2. the mivec cam profiles is for the evo x engine only specifically because of the T/C I/C thus lower compression ratio and different timing angles at different conditions.
3. the evo x engine runs on full time 4wd which means the power output is supposed to supply to 4 wheels for the engine to run in a stable condition and better handling.
4. different evo lancer and lancer chassis code may mean different brackets for additional or other components
5. the evo x drive/half shalft is far different from lancer/inspira fitted.
Technically, it may still be done considering you have enough budget and an experienced technician with good knowledge on this mod. But you might also consider safety issues, engine life, fuel consumption, handling problems and chassis problems. Just my few cents of what I learned in the past week.
