No I don't think so
@Guynextdoor2 that would be a nightmare scenario for the IAF's logistics, an absolute nightmare!
The DM has already stated there are too many different types of fighters in the IAF and they need to simplify the supply chain, no way are those comments about the Gripen or Russian fighters statements of intent- more like posturing for both the domestic audience (ahem HAL) and the foreign audience (Franch Govt/Dassualt).
Let's see what comes out in the next 2-3 months as the govt-govt talks reach their conclusion, nothing I have seen has made me doubt more Rafales (a lot more) are coming to the IAF and will be built in India. Who build them, the industrial benefits they bring, the cost to build in India and ToT are what is unclear as of now.
You call this the Mk.1+ but this is effectively the Mk.2 which, In my opinion, is going to be accelerated by HAL now under pressure from the MoD.
