You should be able to do exactly the same thing with stock calipers/disks -and your limitation appears to be stemming from a lack of vacuum assist. While 930 calipers and a 930=compatible master cylinder will get you to the same place, the primary benefit of 930 calipers and disks (yes, yo will need to change disks too -- this gets $$$$) is fade resistance.

Recommending a specific MC for your application and retrofitting vacuum assist to your early SWB car is beyond my (very limited) scope of knowledge -- but others should be able to easily chime in -- and get your desired result (increased stopping power, not increased fade resistance) for a lot less $$$$ than a 930 brake retrofit
It's a fairly complicated procedure to add a vacuum booster to a non boosted 911
