Welcome to the forum for starters.
This can be a pretty easy swap, depending on exactly what you are looking for. A complete swap with electronics isn't too difficult to do, only thing I would be concerned with is the oil pan, transmission, and fuel pump. I don't know for sure if the oil pan bolt pattern is the same for the Magnum and the LA, gasket is definitely not the same, but there may be clearance issue with the sump, but pans can be altered easy enough if you have access to a welder, people do it all the time. The 727 in the RR will bolt to the Magnum without a problem, you might have an issue with the speedo depending on the year of the Magnum transmission, they became electronic after 1993(?), but the 727 will work just fine, gear ratios will remain the same. The Magnum does not have a fuel pump in the timing cover, the pump is in the gas tank. That may be a difficult thing to alter in short order, but there are proper aftermarket in line pumps that can handle the (45-55psi) pressure, a little extra plumbing may be needed, you may or may not have enough lines running back and forth, just use the truck lines and canister. Now, the interesting part will be how much electronics you want. The computer/engine/injectors/sensors harness is not bad at all volume-wise, at this point a wiring diagram would be needed to identify what is needed and what is disposable and how to power it. I would not try to swap over to a carb, electronic ignition (even though you have that distributor in the RR), and low pressure fuel pump (electric). why waste all the advantages of having the good running electronics. Last thing to check is the hood clearance, which is probably close with the Magnum barrel intake, but still a slight concern. It won't be a five minute job or even a weekend job, but it would be worth the effort, and exhaust should not be too bad to deal with.
