Let me be the first to tell you to get a bigger case and take your time populating it.
I agree that Data is educational and useful (I have one myself for those reasons) but you can't really afford the space. I would suggest Pam's New Workout, which gives you clocks and a whole lot more. Either Pam's or Data can do the clock divisions of the A-160 on their regular clocks. If you have an irregular gate sequence you want divided, that's another matter. You should go for the A-160-2 instead of the A-160, and Quadrax instead of Quadra. Pam's can do basic logic, so hold off on the 1U logic tiles, maybe. I wouldn't choose Plaits and STO but you know the sound you're looking for. Maybe consider Dixie II+ instead of STO. Just Friends and W/ are unobtainable and probably will be for a while, and René is pretty hard to get hold of.
Edit: you're going to need VCAs if you want to use those envelopes to shape sounds.
