I've worked on, stripped and rebuilt a 1ZZ-FE and in the process of rebuilding and modifying a 2ZZ-GE so I would class that as having experience although I admit I don't have any at attempting to cross polinate the two engines together. 

I'd have to go and properly examine both engines to be definitive but intuition tells me the fact the bore and stroke alone  is different between the two motors it is going to be very problematic if not next to impossible. 

I will come back and give a more comprehensive answer after looking at both and determining where the actual problems will arise but what is it you are actually hoping to gain from marrying the two or is simply you have a 1ZZ-FE bottom end and wonder what if?

The photos above were taken earlier this evening.That is a 2ZZ head with the head gasket for a 1ZZ laid over it.While the bolt holes appear to line up fairly well many of the oilways and water passages don't so the 2ZZ head would require modification to align everything up.

Also,it's not obvious from these pics unforetunately but 2ZZ combustion chambers are s good bit larger than the 1ZZs.You would require them to be reduced in size basically to the reduced bore size of the 1ZZ .
