Suggestion for USB PD Trigger with gimmicks

[DatanoiseTV]

It would be nice to see also a PD Trigger with a cheap MCU which allows to set a target voltage, but with
a buck and boost converter on board, so if the target voltage cannot be negotiated, it will be regulated
trough a buck / boost converter.

Another great application would be adding a charge pump to generate negative voltage. This would
be a great addition to a bi-polar bench power supply for breadboards etc. (e.g. +/- 12V for operational amplifiers).

Inclusion of DC load?

Hi, yes that would be great. You can find a version without buck/boost here: https://github.com/wagiminator/ATtiny814-USB-PD-Adapter. The much more complex story that you propose probably contradicts my personal design requirement: It has to be able to be realized in one weekend.
