Window motors have to keep the window hard up against the seals of the window even when the car is going down a bumpy road or else the car will whistle at highway speeds. Some window motors do this by having a very shallow worm gear that is inefficient enough that it won't backdrive even in the presence of typical car vibrations. However SOME window motors do not have this (sometimes because the engineers just goofed sometimes because the engineer didn't want to throw away that much energy -- they wanted to use it to close the window faster for example). In this case, they sometimes add a "no back clutch*" to keep the window from back driving.
Long story short, some of these no back clutches use pins. You can take these pins out. Can you make your own output shaft and install it as long as you have the motor apart? No, I don't think so. Runs afoul of the illegal motor mods rules.
Sorry.

*Back in my GM days, I worked with folks that came out of the Ternstedt division of GM which was a company acquired by GM largely because they had a
patent on window lift system that didn't whistle when you went down the road because it had a very clever no back clutch inside.
