I'm not an expert in mechanics so i'll give my opinion just on the electronic side:
3. At first sight it should be possible, the controller has the same signals. Some changes to the firmware may be necessary for polarities and of course an adaptation PCB would be needed.
4. This page have many useful indications:

Designing a single big PCB heater would be quite expensive for the prototypes, if you want to go this way it would be probably better to use an array of 4 or 9 of them.
A couple of considerations: that's an awesome print area but you might consider using a larger nozzle to extrude otherwise it will take ages to print. There's a video on YouTube of something similar and a big print took 3 days to complete. I think the required precision is related to the size of the object so if you print something bigger it needs less accurancy.
The heater will consume lots of power. And this is another reason to try to get fast prints. You should probably close the sides with transparent panels to create an heated chamber so the heat will stay there: this also reduces power consumption for a print as the heater will be powered for less time.
