Curiously l had considered the Nav light option as a power source, but decided that would be too intrusive.
In terms of risk management having the external battery inaccessible during flight; l concluded that since l routinely carry equally hazardous material/ spares in the forward baggage compartment on most flights, adding the battery to that risk profile, especially considering it is not being actively charged was acceptable to me. :)
The accessibility of the camera via WIFI is very practical and negates any need to interfere with the pressure vessel, which again would be IMHO a step too far to achieve what l am after.

an array of smartphone lenses from old phones and connect them through fibre optics into the aircraft
How would one send an image through a fibre? AFAIK there is no way to do this purely optically, other than by having a bundle of fibres, one for each pixel.
One could transmit a collimated beam through a medium (that’s how film/slide projectors work) but if that meedium is curved, the image won’t be preserved.
any need to interfere with the pressure vessel
You would not need to; the nav light power is available at the wingtip. The data connection to the camera would remain the same; just the power issue would be solved. Then you stick a huuuuge SD card in the camera and just leave it running the entire flight and forget about it.

This option would require penetration of the pressure vessel. :-)
