Fit a slightly bigger fan and adapt the pipework. The worst which would happen is that the air would whistle as it went out.
...Which would require a 12v supply.
Easy solution would be a standard ventilation fan, but to install it in a room sealed box - such that it would blow out through the existing duct. It would be anywhere near as efficient as one fitted in the correctly sized duct, but it would work and solve your problem.
Another way would be to use a cooker hood and adapt the outlet of that to fit your existing duct.
4" ducted fan and a reduction manifold?
80mm 240VAC fan?

Never, ever seen one.
5" (-ish) square 240v ones used to be quite common in the days of mainframe computers.
