The configuration GCodes in RRF2 were not flexible enough to handle Duet 3. We also had RRF2 users complaining about the lack of flexibility in allocating pins to external devices. The changes we made in RRF3 address both of these issues.
The limiting factors are likely to be the LEDs (which are typically rated to 85C - although you might not mind if they failed) and the stepper driver IC because it will self-heat (it will start to issue warnings when it reaches about 100C). However, in a heated chamber you will be limited by the temperature rating (typically 85C) of the extruder drive motor anyway, which also self-heats.

Yes, if you use RepRapFirmware 3.
You can prefix the G1 command with G53 to make it ignore the tool offset.
G17 is implemented. Do you need G18 and G19 as well?
RepRapFirmware has supported that ever since filament monitor support was implemented.
Use pin name “out9” or “laser” or “vfd” in M453 or another appropriate command.
Yes the bed heater input is OK at 36V. The mosfet is rated at 40V.
if you have a Duet 3 rev 1.0 main board, there is an output marked LASER/VFD. Use it to provide the input to a PWM to 0-10V converter.
Yes, we have plans for this.
