Unless I2b split from I2a near the Bosnian refugium and headed to Germany and later I2a spread from the southern Balkans towards Moldova lollll.....a complicated question this is
    Your suggestions would make more sense if the Dinaric branch of I2a and I2a were equivalent, but they're not. I2a-Din is far downstream of I2a itself (assuming you define I2a as P37.2+ here). It's therefore not correct to try to extract where I2-P37.2 and I2-L35 split by taking the Dinaric branch of I2-P37.2 as representing I2-P37.2 as a whole.

    Instead, you need to walk back along the I2-P37.2 tree until you get to the root. At that point, you will have extrapolated the approximate geographic branching location of the two major branches using a formula that looks like: (((Dinaric+Disles)+Isles)+NF+F)+(M26+(Western+Alpi ne)). To me, it looks like the greatest diversity of the (((Dinaric+Disles)+Isles)+NF+F) branch is France, considering that 2 of the 3 components are in France, and the third has a huge geographic range that includes France. The (M26+(Western+Alpine)) branch similarly has the greatest diversity in France or Germany with some certainty. So, a wiser guess would probably be France or somewhere nearby for the P37.2 branch. Doing a similar calculation for L35+ gets you to a similar area, maybe Germany or nearby. So, unless better data comes in to contradict this, we're probably looking a branching location in France, Germany, or nearby, rather than the Balkans.

    What is the original source? It's a bit difficult to read, but looks within reason if I'm reading it correctly.
