In PFF, one of the users have done this. It is now officially registered and passed TÜV.
It costs in Germany around 9000 eur. Some parts were not sold by Porsche to outside, hence they were produced in CNC. But no Isofix as it rrequired welding. He wrote that kids are over 10 years old.
I am considering as well. Including a foldable front passanger bucket. I have the non-foldable buckets.
That's fantastic news that someone has gone through and done it properly. Maybe this will lead to more information about the process so people in other regions could do it if they really want.
Short summary for US audience: cost approx $10,000 USD, a few parts had to be custom CNC milled, and it does not linclude LATCH connectors because that would require welding parts to the body. (increased cost and would make it difficult to return to stock, also might not be legal in the US)
I wonder if we could start a group buy on this to entice a vendor to take the leap?
The first step would be to figure out if the changed needs to be approved by any regulatory agency and how to do that. Above they mentioned "It is now officially registered and passed TÜV." but I'm not sure how to do stuff like that for non-classic cars in the US. Or maybe it would be easier to have the work done in Canada? USA will be tricky because of liability nonsense. Someone find a shop, point them at that thread, and ask how much.

You have to register every change in the car at TÜV in Germany.
Even if you chnage the wheels. There are very few which doesnt require a check.
Otherwise the vehicle will be classified as no license to driven on public roads, that kills insurance or pretty much everything.
OP, This is just an all-around bad idea. Consider a different car if back seats are needed.

Safer but with seriously limited egress options. In a side impact the rear may be a trapped space

Much like a roll cage, halo seats or hans, however, the better solutions would necisitate compromises and investments most would be unable or unwilling to make in a street car.
I'm sure there would many people interested including myself. Glad to see the thread went back to talking about what the art of the possible is vs the legal implications of it. The body is the same and many of the trim components are common . This won't be something impossible and can be just like factory since it already exists on another vehicle.
I've looked into this for quite a while now (since my 996.2 GT3) and since my child is now only 7, she could stay in a child seat w/ built-in 5 point harness and I'd only need to use the LATCH system of the child seat to attach to the car. The top LATCH anchor is left there for all to see, but the bottom two anchors are missing. So my initial thought was to change the passenger LWB to a sofa for easier access, and then get the lower anchors welded back onto the car. But after mulling this over for weeks, I decided to just buy a Carrera T in PDK for me and the wife to haul the family around instead, and keep the mileage of the GT3 low.
