I think it’s a great idea. I first started learning Dutch with Michel Thomas audio course which is very much about being in a simulated small language class, and you need to say sentences when prompted by the “teacher”. Later in, I learned almost all the Dutch I needed to pass the citizenship language exam just by conversing with friends and family in Dutch, gradually building up fluency. Let me know if you need a beta tester, email is davedx@gmail.com
