Your over thinking!! lol!! So long as the neutral is the same size as the phase conductors it's a good-un!!

would not the CSA of the neutral be an issue though? not being ballanced etc?.......

Neutral current won’t be a problem. If your boss is prepared to cough up for 4mm I’d not argue with him. Big is beautiful in my book.

Don't forget to rate up to take in to account the temp, kitchens can get VERY hot, especially behind an oven.

I tend to use SY when wiring ovens as the additional protection is worth it in a kitchen.

Regarding the neutral current you have confused me. There is a good chance the oven would be phase balanced (it would be if I designed it), so the neutral is theoretically not required. So why do you think you need a larger neutral than line? 4mm 5 core SY would be what I would do, but if singles I wouldn't drop the N/E to what the calcs say (prolly a lot smaller).
