I am planning to replace two two-way switches that control one light with smart switches [that also have touch switch built in]. I want to keep the existing wiring and switch locations (i.e. hall light with upstairs and downstairs switches).

Would this be better served by a master-slave configuration, a scene configurator or 433Mhz slave?

What would I need? I'm planning to use Amazon Alexa for the control in a European live/neutral/earth environment.
