This is a very interesting discussion, as I stand for the same problem.
First problem is, that I have 14″ Revolution wheels and I will not change to 15″ or 16″. Therefore the space for the brake is limited.
But for me the most important thing for tuning a brake is to fit a bigger vented disk. I think, it makes no sense to fit other calibers on the original disks. It would be better to fit bigger disks with the original calibers.
The second reason is the price. I think it would be easy to buy a complete set from dale`s restoration for 820 Dollar and install this parts and everything is fine. But this is a little expensive I think.
Therefore I will look at some other parts (maybe I will get some brembo calibers) and I will test some disks to see what will fit without much work.
I will tell you then the results.
By the way, I see no problem about the brakebalance when fitting a stronger brake at the front. It would be a big problem to fit stronger brakes at the rear because the badest thing is a overbraking rear, but on the front, I see really no problem.
