After creating a custom logotype, I used the rules applied to the letterforms to create a consistent, custom typeface, based on Aktiv Grotesk. The below ISSUU document outlines the differences and changes made.
The typeface is also fully usable as an OpenType font, using the same metrics as Aktiv Grotesk.

Below are all the characters that were changed. These will then replace the existing letters of the typeface.
