PE-3 KISAW rebuild

As stated on my Forum on SP, I rebuild the PE-3 KISAW from No Man’s Sky in SR2 (since it’s a Spaceship). I am finally done rebuilding the Seat:

I will only need to scale it all down to get a semi-realistic Size.
And that’s where you come in. I haven’t found a Way to shrink everything at once without having to shrink every Part and putting it back together, so I wanted to ask if there is a Way to do it on Mobile or with Overload etc. If so, please let me know in the Comments!
