cdietl As far as I know, it was never the intention to change the font. Therefore, we would first need to carefully assess what exactly would have to be adjusted. The current font harmonizes with the overall portal design as well as with the user dialogs - and it should also be accessible. Changing the font could tear the design apart, as a font defines letter spacing, stroke widths, x-heights, and more. This would also mean that process developers would need to maintain the branding configuration in their designer installations so they can properly develop the user dialogs with the correct fonts.
Why would you like to change the font?
