I'm using "baseplates" for my builds which are built by using two 16x16 plates with one brick height between them (to connect multiple baseplates with Technic bricks and pins).
Now I'd like to build "edges" on the sides where no further baseplate is connected. The problem is, that, although the baseplates have a height of a 2xX plate, I cannot align them correctly centered.
Is there any SNOT technique to get the 2xX plate aligned as for (A) which I cannot use, because modified brick 32952 does not fit between the two plates of the baseplate. For variants (B) modified brick 87087, and (C) Technic brick with modified tile with pin 2460 the attached plate would be slightly displaced.
It doesn't matter whether the attached plate would be "studs out" as in (B) or "studs in" as in (C), as long as it aligns as in (A).
(Bonus points if all bricks needed are available in white.)
