sounds like a great way to experience it first hand. If I were you I would try pseudostuttering in various levels of severity and type (repetition vs blocks), and plan it beforehand (like a 5 second block on the word 'hello', 'you', and "something" in "hello can you help me with something?") because I can guarantee you if you don't plan it your anxiety/shame will make you want to get out of it asap. If you're brave enough you can even try stuttering on every word for 10+seconds in front of multiple people. And something to keep in mind when you are in that 5-30 second block imagine what it would be like to not know when it would end. What makes stuttering so difficult is feeling completely helpless in a block. That's why you won't really be able to experience what it's really like but it will give you an idea. good luck and please report back about your experience :)
