I absolutely love Pollen. Do it! I switched away from Racket because I wanted less moving parts. With Lua (a language I know better than Racket) I feel I have a better grasp of all the parts. The main reason to switch away was to make the codebase smaller and easier to tinker with, but the pollen version was great.
Fennel is absolutelly amazing, I love it. I just didn't had the need. I like Lua the way it is. I was a student at PUC Rio for a while, I fell in love with it there and am very familiar with it.
