The actual soviets - they remained in operation for the first few years after the Bolshevik coup, and the revolutionary slogan "All power to the soviets!" gave Lenin a convenient figleaf for sidelining the elected Duma.
Of course, the soviets also proved unwilling to entirely subjugate themselves to Lenin's whims, and made a habit of choosing non-Bolshevik delegates. This culminated in the failed Kronstadt rebellion of 1921, after which any pretense at democracy was finally ended.
But - in theory - the soviet model sounds akin to what you're looking for. Being made up of delegates rather than representatives meant that the power of recall on demand was baked-in at every level, and power flowed upwards to a strong executive leadership.
In reality, it's hard to see how any sufficiently strong leader wouldn't be able to override or simply ignore any sort of kill switch or other constitutional arrangements that might happen to stand in their way - as has happened every time it's been tried in the past.
I think the person elected should hold a lot of powers. Because otherwise, what is the point of voting if they're just going to leak it all to the civil service?
By "kill switch", I just mean you need a way to stop a leader with a lot of powers in exceptional circumstances - such as violation of a constitution.
