replace individual 1n4148 with diode array
Diode arrays are pretty popular, and you can find them by searching in Digikey etc. 

Here is one line-up of Schottky diode arrays from one manufacturer: 



BAV70 and similar are regular switching diodes (not Schottky). 

Machine-populated SMT 1N4148 diodes may be more economical and may have other advantages as well. 

The below search is sufficient to constrain it to only 28 results out of almost 12,000. Further distinctions include package and Schottky vs. regular as well as manufacturer, price, stock level etc.
