Go ahead with controllers you´re feeling most comfortable. ;-)

Please let me know if there is any success with the teacup SCARA. I am mostly interested in that.

waiting for some coding wizard to put that into firmware

Why would a developer do this? You created the trivial part, the mechanics, now it's time to approach the challenge. Regarding Teacup I'd start with turning on debugging messages in dda_create() to see which movements come in, to how many steps this is translated and what the timings are (dda->c, dda->c_min = time distance in CPU clocks between two steps of the fastest axis).

Because the "trivial" mechanical design is pretty much where my knowledge/skills stops, if at that.

Does your boat have enough time for learning coding?

I don't dare to warm that up it will just become gelatine.

Warming the bearing housing makes sense too ...

The problem with stacking everything up is that bearings will never go perfectly vertically in the hole, they will go into an angle with the increasing pressure and that might crack the plastic. Having it from the freezer might help.
Wobble will not ruin the printer ... I believe it will have a small toll on accuracy (whichever that is).
Heating bearings?!!
For my setup I need a shaft/rod/bolt/etc that is threaded at the ends so I can clamp down the stack. M8 standard is actually less than 8mm by quite a bit. But I don't thik that will pose major problems because as the tensioning spectra will pull the drum towards the bolt on the motor, the bearing will sit against the same side of the shaft/rod and that will only decrease my arm length by 0.2mm maybe. The tension will always keep it there.
