Hi,
Everything can be done with sufficient amount of money and this is an DIY, if you have the time and inclination.
If you compare RH/LH SNs on realoem, you’ll get an idea of how extensive the list is of parts will be, and that most of those parts are out of production now. With the pricing of these cars, buy a similarly speced, cheap LHD donor car for parts. Then, in your RHD zed, disconnect battery and remove the sw airbag. Unbolt your steering wheel. Remove car and replace with donor. Steering wheel bolt back on, airbag back on and connect battery. No coding necessary.
