Won't work. The new Mac mini does not support using an iMac as a display.
carefully read > Use your iMac as a display with target display mode - Apple Support
You need an external display for the new Mac mini.

Not possible unfortunately.
Nope.
the good news is a normal monitor would use a fraction of the power of the imac so you'll save on your electric bill
