Give it a go, but have patience. Don’t start during a particularly busy time at work, and be prepared to switch out your keyboard for a full sized one for 30 minutes when you get frustrated.
If you’re going directly from 104 keys, it’s going to be a big change. It will take time to build the muscle memory. But good luck!
This is similar to how I learned Miryoku, I slowly migrated my TKL board over to it incrementally. First I dropped the number row and did a Planck-style layout, then once I was comfortable with that I added homerow mods to it, then once that felt good I did what you've done here. After those baby steps, I built a Fifi keyboard. I've been on Miryoku for about two years and am stoked on it (although I've recently adapted it down to 34 keys and like that better)
You've got this! Like the other commenter said, be ready to take it slow. Also, if you haven't already, print out a cheat sheet if you think that would help. It goes a long way.
