This "not fully man" because He had no sin nature is strictly my own invention.Well, yes, but only in a sense that peripheral to what people intend to convey when they say that Jesus was "fully God".
As "God in the flesh", Jesus did indeed have "limitations" - I suspect that He did not, for example, know about the theory of general relativity (as God the Father arguably would). So when we assert that Jesus was fully God, we are not suggesting that He "escaped" some of the limitations that necessarily accompany embodiment.
I challenge your assertion that He did not have man's "sin nature". While this is not an area I have thought about, my gut response is to suggest that Jesus did indeed "have a sin nature" in the sense that He "inhabited" a body and a brain that was subject to all the temptations that we are.
In fact, this text from Romans 8 strongly suggest that Jesus did indeed have "sinful flesh", even though He was without sin:
For what the Law could not do, weak as it was through the flesh, God did: sending His own Son in the likeness of sinful flesh and as an offering for sin, He condemned sin in the flesh,
I suspect you might say "in the likeness of sinful flesh" simply means that Jesus only appeared to have a sin nature. Well, that is a little hard to sustain in light of what Paul writes next - on the cross, God condemned sin "in the flesh".
This appears to be a rather clear claim that there is a sense in which sin was in Jesus' very flesh.
I've never heard of it anywhere. It's just a little pet theory of mine.
