I think that Signature Plastics should offer blank sets of DCS keycaps in PBT plastic, just like they do for DSA profile.
And in ISO layout.
That would be much more desirable for many ISO folks than the double-shot DCS keys in ISO that often have the wrong legends for them.
I think this could be great as replacement caps for the CM Storm Novatouch because the keys are lower than OEM profile but without internal struts so they wouldn't bang into the switch tops even without O-rings. The profile and texture of the keys are also quite similar to Topre Realforce caps.
