Full Wave double diode detector +6db gain

[KX4QC]

Most non-FM detectors work by half-wave rectification of the RF signal, passing a stream of RF one-direction pulses that are smoothed to an AF tone.
What about the other half cycle of the perfectly good RF signal? We deliberately lose it! Duh!
This circuit uses two half-wave font ends in antiphase, so that a double sideband with or without carrier produces rectified AF from both half cycles, making a louder signal, and presumably improved SNR.

What's the downside? Two, rather than one tuned circuits and one more diode than usual.

It got me thinking that the approach would work well with other common half-wave detectors too. Could it be adapted to work with a regenerative circuit with a single tickler coupled in antiphase to each tuned circuit? The one needs to consider how to minimize the Q-damping effect of the detectors (? FETs, ?Darlingtons...) I feel an experiment coming on....

Well, what do you think?
