Such a project is not simple. The Globe motor planetary gearbox uses a powdered metal ring gear which engages with a serrated feature of the motor endframe and is held in place by roll pins. It is fairly convenient to replace those pins with small screws if you want to disassemble, modify the gearbox, and then re-assemble to the original motor. (Many teams did that back in the day.
) However, assembling the gearbox to a different motor will require some cleverness.
Also consider that the Globe was designed as a totally-enclosed non-ventilated motor, and the RS-550 or AndyMark 9015 are designed for flow-through fan cooling. This means you shouldn't block airflow at the shaft end of the motor.
Taken together, these two factors will make it a challenge to use a Globe gearbox with an alternative motor. A COTS planetary, like those offered by Vexpro or AndyMark, would be a better choice.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
