Why the proposed Victory suffix is 1805

Why would a proposed renaming use Victory 1805 rather than her launch year?

1805 would commemorate Trafalgar and make the change more acceptable; Victory's continuing commission also distinguishes her case from Belfast.

Adding 1805 to the historic Victory's name would associate her with Trafalgar, rather than simply recording her launch in 1765. That association is proposed as a way to make a name change politically acceptable. The idea is tentatively attributed to Andrew Lambert. A comparison with Belfast is rejected because Victory remained commissioned, whereas Belfast did not.
