Well, I'll jump in here with MORE than a "full monty" option, but it won't be available for several months (at best) and will certainly NOT be a DIY project.
I am intimately involved with the "Dynon Certified" project and am currently working on the M20C, E, F, G prototype for earlier Mooneys, using a 1965 M20C aircraft.
This will be a complete makeover (with possibly some surviving avionics) and cost less-than-half of a similar project using new Garmin equipment.
This ambitious Dynon project was announced at OSH 2017, but keep in mind we are still in the development stages for STC approvals (Mooney and other aircraft) and we have no projected availability dates as yet... even though the FAA is being very cooperative.
These installations will need to be accomplished at "Dynon Certified" facilities, being established across the USA, and will be carefully monitored for quality control.
I've included three preliminary examples, for the Mooney M20C panel, featuring our flagship SkyView HDX displays. Please excuse the crude resolution of these .jpg files. Our engineering file format is not compatible for uploading here.
These examples include full IFR capability, dual ADAHRS redundancy, remote compasses, Mode S transponder with ADS-B In/Out and a full-featured autopilot with GS coupling. With our STC approvals, we should be able to accommodate most of your requested configurations.
Whew... that's enough for now... stay tuned.
