Signature Plastics doesn't do doubleshot PBT and you can't dyesub light legends onto dark base caps, so this colour scheme cannot be done in PBT, regardless of the profile.
It could be done in ABS doubleshot, but if you choose DCS profile, I don't think it would sell too well, as DCS caps are thin and have a sharp angled bottom two rows.
You could try run it through GMK, but they've got a very high MOQ and I'm not sure the colour scheme would be popular enough. Sorry.
