This won't happen spike, the armour pieces have large pegs which are glued into holes in the body (assuming this is constructed like the P2 maquette) Plus the material is very brittle and easily snaps as I found out. You will not be repositioning any of the armour on this.
I wouldn't be so sure of that, this one looks really nice for sure and is a viable alternative, even companion piece to the original maquette. But the selling point of the SWS maquette is its pedigree, it will forever be the only 1/4 P1 produced with and under the supervision of the man himself. I prefer the pose on the new one no doubt, but the mask is much better on the original. This new maquette, as nice as it is will never feature in a picture like this...
