Plans to resurrect the Nomad N-24 as a modern day aircraft with improved engine and avionics never appeared to progress much past wishful thinking.
And I have heard more than one person heave a sigh of relief about that!
The same people also mentioned that it would have been a better 'thought bubble' if they had considered building something like an updated Chieftain, or a C402 etc etc.
As for whether or not such an aircraft would be viable I have no idea.
