Lots of legal obstacles, best check with your local dmv and epa office.

Different computer, probably harness changes. Like previously stated, state emissions inspection program will come into play. If you don't have an inspection program in your state, there is a lot of talk about using 4.7 computers with Gen III Hemi's. Might be a straight drop in for your Durango.

If you swap to a LA engine, you will need to swap over the computer and engine wiring harness, which will have to match your year and be dakota/durango. Since the 5.2 wasn't available in 03, such an ecu may not exist. I suppose a 5.9 ECU with smaller than stock injectors may work fine, or stock injectors with a recalibration.
You could drop in a carbed of aftermarket EFI'd engine, however your transmission would't shift, your gauges wouldn't work and it would be useless. You could send your computer out to be reprogrammed to compensate for this, however you would at a minimum need to hook up a throttle position sensor to get your transmission to shift.
Alternatively, you could gut ALL the electronics out, run aftermarket gauges, run a manual transmission or pre-electronic transmission (1995 and earlier) and eliminate the computer system all together.
This of course all assumes you have no emissions testing or inspection.

The 4.7 computer in that durango will run a 5.7 hemi but not an 5.2 or 5.9 just sayin...
A 5.9 computer runs a 5.2 just fine.
If you have a grey key it gets harder swapping engines from one family to another as there is a chip in the key and all the confusers have to agree to let the engine run based on that chip matching all the computers.

The title says dreaming, sounds more like a nightmare. LOL Yeah, I think you're right. When the time come, probably just look for late model stuff to replace. Thanks for the replies Scott
