1942 - Spit F IX (May 1942. 81 SQN The British Fighter Since 1912 Mason)
1942 - 109G-2 ( June 1942. The first units, III/JG 52 and I/JG 54, received their G-2s in June 1942. The first loss reports are from July 7th and 8th 1942. Prien & Rodeike)
1943 - Spit LF VIII (?)
1943 - 109G-6 (G-6 Entered service and saw action with II/JG 53, II/JG 77, JG 27 and JG 51 in February 1943. Prien & Rodeike)
1944 - Spit LF XVI (18 lbs boost ?)

Late 44 - Spit F XIV (21lbs boost ?)
For the 109s the best choice for a new variant would be a Bf 109G-14. About 5500 made (abt. 1000 of which were G-14/AS versions).
If they were to split the G-10/K-4 hybrid into actual variants (G-10 around 425 mph / K-4 452mph) then the G-10 could server as a sub for the G-6/AS and G-14/AS. If they model the K-4 based on C3 + MW50 at 1.98 ata then it should be perked (maybe a small perk anyway).
A few 109s that would be useful for scenarios / ToD would be the 109E-7 and 109F-2. However, these maybe a bit much given the work load.
The Spit fans will have to fill in the blanks above in regards to service entry dates. There's talk of adding a Seafire L.III @ 18 lbs boost as well. I am not sure where that plane would fit in...
The dates are service entry (just did by year and picking the most produced version of Spit).
Seafire L III would be Med/Far East.
If it helps
This is from talking to Pyro what he is planning, so fill in 109/190
1940 - Spit I 12lbs / 109E4
1941 - Spit Vb 12lbs / 109F4 + ?
1942 - Spit F IX / 109G2 + ?
1943 - Spit VIII 18lbs (no real LW opponent so pick 2 historic opponents for LF IX) ?
1944 - Spit XVI 18lbs (poss 25lbs, more historic) /?
1945 - Spit XIV 21lbs (more XIVs in 45 with 21lb than 1944) / ?
These are the most produced Mks for each year, instead of the lets have Vb, Vc, XII etc.
