Next-Gen Lexus F Thread

It seems that the front part of the suspension and chassis came from the GS, the midsection from the IS C and the rear parts are from the 3 IS. How that can be efficient, I have no idea, but clearly Toyota knows more than I do.
I can't help but wonder if a different platform configuration (all or mostly based on IS or GS), might have made this car lighter? Piecing together parts from three platforms and then welding/reinforcing them together can't be light.

This is what I found about the RC at Car and Driver:
The IS C donates its floor pan (with reinforced sills), the GS its structure forward of the A-pillar, and the IS its rear architecture.
From this, I gather that the RC sits on a strengthened IS C floor pan (shortened IS pan?), with a front end structure (frame rail extension, engine mounts and suspension) from the GS, and rear suspension from the IS.
If the 3IS was not designed for a V8 engine but the 4GS was, it makes sense that the RC (and RC F) uses the GS front end.
No, they won't be cutting and re-welding together IS floor pans to make the RC. The "cutting and re-welding" would have been done in the design software. The IS C is derived from the IS and the IS is derived from the GS so it is all related and all fits together.

From what we've heard around the rumor mill:
LS500 (5.0L V8) 467hp*
LSh (3.5L V6 Hybrid) 500hp*
LS F (TT5.0L V8) 600+hp*
