would it be possible for team daidalos to include the spit mk1 in a up coming patch please

Probably not. Oleg/1C refuses to release any map or plane which might compete with the plane set in SoW. Since the Spit MkI is quintessential British Battle of Britain fighter it definitely competes. If you want your early Western Front plane fix, you're stuck with mods.
