RHD driver's seat as LHD passenger seat?

I got my hands on a scrapyard driver's seat from a UK Prius, same as mine just mirrored. I'd like my wife to enjoy the benefits of manual height adjustment and lumbar support (her back hurts often on long trips), so I've asked a mechanic to:

- take the original, great condition LHD passenger seat apart, leather covers, cushions, airbag, heating, sensors, safety belt att. etc

- take scrapyard, super dirty RHD seat apart, remove rust and dirt, use seat bottom frame with the height adjuster+plastic bottom side cover panel + adjuster handles + the lumbar support mechanism from it, throw away the rest.

- add these parts to original seat, keeping as many of the original LHD parts as possible.

Now, the bottom rails of the RHD seat look REALLY dusty but I'm told it's only superficial rust...can this become a safety problem?
Forward - backward adjusment works fine so it's not like it's stuck from rust.

Is it easy enough to feed power to the motorised lumbar support somehow?
Am I going to run into problems with the detection sensor, the airbag or anything else?

Are there any potential red flags I should be aware of?

I think it shouldn't be a problem from what I can tell looking at the diagrams. Both seats have the same airbag position, connectors and sensors if I'm not mistaken. I'm attaching the diagrams I found.

I don't think height adjustment of that level is feasible with any add-ons.

Thank you! That's exactly the kind of crazy leftfield thing I never would have thought of...now I need to look into this.
What's the role of the occupant classification ECU - is it the thing that determines whether the seatbelt sign needs to switch on for the passenger?
Does it arm the airbag?
Anyway it sounds important and a pain to recalibrate. I'll definitely look into it.

So here's the first picture from the shop - looking promising! I'll have to see it in person to report in more detail.
