So, is it possible to down convert but retain the wide color gammet content? If so, how should I setup the MadVR HDR settings? I'm running win7 to a 1080p Denon receiver (which prevents passing 4k to the projector.

You can calibrate your display for a wide color gamut in SDR mode (e.g. BT.2020), but the brightness will still be lacking. And your AVR may not passthrough the gamut. You would have to test. You would be referring to the HDR -> SDR conversion feature of madVR, which will passthrough the original gamut if you set this display is already calibrated to DCI-P3 or BT.2020 and set HDR to convert to SDR with pixel shader math.
However, before you test, you will need a graphics card with a 10-bit HEVC decoder, as your current card will not be able to downscale 4K -> 1080p, nor will it be able to decode it.
