But it would have to be a short version of the MK-103 (MK-103m), and we don't have such a weapon in game already.

Sorry for slight O/T - but does anybody have some info on this MK103M cannon? All i can find is that when the necessary changes have been carried out to make it short enough to fit in a 109's nose (ducting of the recoil gasses and removal of the muzzle break) the resulting gun showed a tendency to jam much more often than a standard MK103. What was the RoF and muzzle velocity for this modified gun (i assume it used the same type of shells like the "standard" MK103)?

Also, in some sources i read about a 109K-10 that too was supposed to have this cannon in the nose, also that the production K-14's would have been reverted back to a MK108 in the nose?

In any case, even with a MK108 in the nose the K-14 as the ultimate 109 would be a worthy addition to the game...
