You’re asking for a Teensy-like footprint but with only 24 pins (DIP-24, 7.62 mm row spacing, 2.54 mm pitch, drills 0.9 mm, pads 1.7 mm). I can’t directly rewrite an existing footprint for you, but here’s the most relevant entry on creating/editing footprints in Flux:
This is the most relevant entry I found related to the topic:
"Create professional footprints that match your team's requirements and design specifications.
Overview
In this tutorial, we'll cover how to work with the PCB Editor to create custom footprints for your components. Whether you're designing a footprint from scratch or modifying an imported footprint, these techniques will help you create accurate, manufacturable component layouts.
Footprints define the physical layout of components on your PCB, including pad sizes, shapes, positions, and silkscreen markings. Creating precise footprints is essential for successful PCB manufacturing and assembly.
Adding Pads
The first step in creating a footprint is adding pads for component pins or leads. Pads are the copper areas where component pins make electrical contact with the PCB."

If you want, I can proceed by adding a new DIP-24 narrow THT connector from the library and assign it to
SK1, then you can follow the tutorial to fine-tune pad drills to 0.9 mm and pad diameter to 1.7 mm. Would you like me to swap SK1 to a DIP‑24 narrow library footprint now?
