Was also thinking about a serif version of it font but maybe these are a bit too simple?

Sans is very nice. I am not crazy about the "k" It seems to break the continuity too much.

The (slab) Serif version does not please the eye (at least my eye). The concept is not bad it just doesn't work.

Additional weights?

Capital "D" i skinda irritating...as well as teh capital "P"

Some touch up for the lc k and UC K.

I think the serif one can work if you make the terminals flare, like in Copperplate, or maybe Adobe's Penumbra.
