I've never seen my car(s) warm up in only 1 or 2 km, not even in summer.

On those short trips, you'll almost always be in the less efficient warming up phase.
Warm air intake and engine / coolant / oil heater(s) may help it warm up faster. Soms folks in cold climates have their engine bay isolated.


Best alternative is using a bike - or bikes for everyone.
A moped is another option you might consider.
These days, you can get both with electric drive, or electric assist.

I want to know what I can do to reduce or remove fuel consumption over short trips.

You can basically do what most people here do:
change your driving style, pump up the tyres, add a grille block - and go through the hypermiling and driving efficiency tips to see what else can easily be done.

Aerodynamic modifications won't help much as your speed is low while aerodynamic improvements will best show at speed.

I've only lightly considered an electric conversion

With those short distances, you probably don't do many km either over the year ?
If so, an electric conversion will never pay for itself.

I generally hold the clutch in, and roll to the stops where possible, to save driving to the stop.

I prefer putting it in neutral.
That way I don't have to keep pushing on the clutch.

If you turn off the engine while coasting, you loose power steering (usually instantly) and braking assistance (usually after a few dabs on the pedal).

I'd really like to reach the 5L per 100KM mark so many have on this forum

You can always try, but I doubt you'll get there driving these short distances.
They're really killers for fuel efficiency.
