I'll try to tackle this (I'll respond in blue)...
First of all, to avoid confusion -- you say "styro drum". I'll say "styrofoam spacer dummy" as drums are professional cake boards (thick foam core sealed in foil) used as presentation boards under cake rather than stacked as dummy spacers.

3" round styro drum
6" SPS plate with columns down through the 10" cake (this is the only place you've listed a plate that shows under a styrofoam spacer dummy -- nowhere else.)
10" round REAL cake - 6" SPS plate with columns down through (No support system required here... dummies don't need anything internal, and you didn't list internal dummy supports elsewhere.)

12" round REAL cake - sitting on the 6" styro drum
6" round styro drum - resting on the 10" foam dummy cake below (there is no 10" foam dummy cake below, it's a 12" square cake dummy.)

6" round styro drum - sitting directly on the foam below
16" square cake dummy
17" plywood base board (covered in foil)
In your photo, did you notice that the Wilton tailored tiers cake display set has progressively larger spacers? It's my opinion that you should use progressively larger styrofoam spacer dummies to avoid this whole thing from looking like cakes are impaled by a giant 6" diameter shishkabob skewer. I'd use spacer dummies 2" smaller than the cake above. (which brings up another point...)
You say you want space to show around each tier for borders and decorations, right? I'd suggest using cake drums 2" larger than the diameter of the cake (they're available in silver, gold, white, and black). So now you'd have 4" of space under each cake drum (between the outer edge and the dummy spacer) for your LED lights. (are these LEDs wireless? If not, where are you running the wires?)
Who chose these sizes and why? Do you HAVE to stick with this plan? It has a nice gradual incline from the bottom two tiers, then it goes straight up for at least a foot throughout those 12" square and 12" rounds, then goes back to a somewhat appealing angle (even though it's not a consistent angle). Personally, Iike 4" between tier sizes (especially when separated) otherwise it looks too tall and towering (and this is not only tall, but is also extremely top heavy w/all weight at top and all dummy tiers on bottom). I'd get rid of all 12" tiers and go w/6" x 10" x 14" x 18" sq x 22" sq on a 26" plywood base, using 4", 8", 12", & 16" dummy spacers (this would allow avoiding the 10" cake's 12" drum from hanging directly over a 12" cake, as well as having the 12" cake's 14" drum from sticking out farther than the 12" square cake directly below).
Speaking of top heavy (especially if you're sticking with all tiny 6" dummy spacers under all tiers), to prevent the top from toppling off -- this should definitely be built on a central pipe that's screwed into the plywood base.

Don't lift it to put a tablecloth under it... place the finished cake on the table only after the table is decorated first.
I think that's all that was on my mind!
Oh, and if you can't find large cake drums, you can make your own from foam core covered with fanci-foil.
