Whilst welcoming you to flyer talk you need to be realistic and the chance of an upgrade is virtually zero.
If it happens it happens (and BA will only upgrade because it has over booked the cabin) and asking won't help because BA has an automated process for deciding who it upgrades and it includes factors such as status, previous flights and class of travel, and fare bucket of your ticket play more a part and being on honeymoon will have no bearing on it (I imagine several other couples will also be on honeymoon flights)
