I was looking to get exactly the same thing this morning plus more. The pricing is not bad, $1 per cap, and it is PBT(my favorite). My plan was to build blank set for my Poker, but as you stated in your post I wasn't able to get the capslock part. Other grey keys are available in GDL color, though. (backspace, enter, L/R shift, and tab.) However, the price gets pretty high if you want to build full 61keys, so I think I will purchase only part of the keys for now.
I wondered how GDL keys looked like on a board, and after looking at your photos I think I will order a set of following GDL keys.
301988 DCS - 1.25X ROW 4 - GREY (GDL) -- (bottom modifiers) x7
212366 DCS - 1.5X ROW 2 - GREY (GDL) -- (tab, backslash) x2
211305 DCS - 2X ROW 1 - GRAY (GDL) -- (backspace) x1
212590 DCS - 2.25X ROW 3 - GRAY (GDL) -- (enter) x1
212370 DCS - 2.25X ROW 4 - GRAY (GDL) -- (left shift) x1
301993 DCS - 2.75X ROW 4 - GRAY (GDL) -- (right shift) x1
210923 DCS - 1.75X ROW 3 - WHITE (WAS) -- (caps lock) x1
Plus some CREAM 1x1 keys.
212013 DCS - 1X ROW 1 - CREAM (WBK)
212015 DCS - 1X ROW 2 - CREAM (WBK)
212017 DCS - 1X ROW 3 - CREAM (WBK)
212018 DCS - 1X ROW 3 HOMING BAR - CREAM (WBK)
212019 DCS - 1X ROW 4 - CREAM (WBK)
Also, I want to mention that the photo of color samples is from kbdholic. I think it is good to state sources when a photo is not yours.
I saw the same picture here:
