Karnak, taking a hint from IL2/FB's naming scheme doesn't necessarily mean AH needs to go the exact same way. I'm certainly no Spitfan.. but I think I'm actually pretty objective and neutral when it comes down to these stuff. IMO the Spitfire is pretty unique, and it needs to be represented as it is.
While other countries would add a different suffix at the tail end to differentiate each of the sub-variants, the Spitfires didn't go that way. The generic term "Spitfire MkV" is about as equal as the also generic term "Bf109G".
Between the timeline of 1941 and 1943 the Bf109s went through F-2, F-4, G-2. and G-6.. just to name the major subvariants. But the Spitfire MK.V didn't go that way. They went the way of LF, HF, F, and continous upgrades in performance but still retained their name, until the Spit9 began replacing them.
So, I don't really think its unreasonable to ask for multiple Spit5s and multiple Spit9s and such. The Bf109G, through 1943 to 1944, evolved from Bf109G-6 to Bf109G-14. Much the same, the SpitfireMkV, from 1941 to 1942, would just simply evolve from the Spitfire F.MK.Vb(+12) to Spitfire F.MK.Vc(+16).
The Gustavs have 3 different models in the game. We're currently asking for a fourth - G-14. So I see no reason why we cannot have a 1941 Spit5 side by side with a late 1942 Spit5.

As for the Bf109G-10, IIRC there is no data on earth that exists confirming that a Bf109G-10 would do 452mph at 22k. Some Bf109G-10s did have the more powerful DCM engine, but most of the Bf109G-10s used the DBM engine, and it's top speed is usually commented at 690km/h(428mph) at 24,500ft.
In other words, our G-10 is not a G-10 at all. It's not even a "top end G-10", because no such data exists for this plane. It's a K-4, and literally.
It's like the IL2/FB Fw190A-9 - a plane that did exist, presumably with very high performance, but no data exists on this plane's performance at all.. and yet, the IL2/FB team decided to just model that plane, based upon guesstimates.
AH was young, the plane set was still small. There was lot to be done, and many more planes to be added. Pyro didn't have the time to put in two late-war Bf109s, so he just tries to kill two birds with one stone, by naming a K-4 to "G-10" and giving it MG151/20 option for the hub cannon.
However, since the opportunity is rising now, to correct the various flaws in the planesets, I say do away with the temporary compromises and hybrids once and for all!
The standard Bf109G-6, is quoted at about 622~640km/h(387~397km/h) at 21,000ft.
The G-14 with the DB605AM, the top speed is usually quoted 665km/h(413mph) at 18.000ft.
And finally, the real K-4, is the only one quoted at true-blue 452mph.
