Hes saying our "g10" is if fact not a "k-4"
g10s were a mixed bag some were refitted g6s some were new some used different eng etc......
109g6asm should be the preferred lw choice for a 109. It would fill the gap between our current g6 and the g10.
But the lw planeset is pretty full. Theres certainly no need for any more "wunderwaffe" planes.
The k-4 has its place but given that other countries lack some pretty basic planes one would hope that they would get attention 1st.
VVS
IJA/N
RAF
Italy
France
US (more early war variants of most of the us set: p38s, p47s, p39s, etc)
Then fill out the german set
109e7b, 109f2 (these two will be needed if early eastfront is developed; plus they have a use in NA) finally 109g6 or g14/asm
190a1 190a2 190a3 190a4 190a6 190a7 190a9 190g3/8
