Using 4 Dual Alphanumeric Display(1907)

[Hexter48044]

I am designing a project requiring multiple 8 character alphanumeric displays and need to reduce component count as well as PCB real estate.
Will the Adafruit_LED_Backpack_Library-1.3.2 support 4 dual alphanumeric LED displays(ID 1907) connected to the Adafruit HT16k33 backpack(ID 1427) as shown in the supplied schematic?

Sample code extract as follows:

alpha4.writeDigitAscii(0, displaybuffer[0]);
alpha4.writeDigitAscii(1, displaybuffer[1]);
alpha4.writeDigitAscii(2, displaybuffer[2]);
alpha4.writeDigitAscii(3, displaybuffer[3]);
alpha4.writeDigitAscii(4, displaybuffer[4]);
alpha4.writeDigitAscii(5, displaybuffer[5]);
alpha4.writeDigitAscii(6, displaybuffer[6]);
alpha4.writeDigitAscii(7, displaybuffer[7]);

It can do two modules. You can see an example of this being done in this product:

Schematics are available here:

That leaves several COM pins unused. So it seems possible. By extending this to two more modules using those pins.

Thank you for your quick response.

Yes I am aware that it can be done with 2 modules as I have accomplished with other projects. However, using 2 modules increases component costs and takes up more space on my PCB, which I have to keep at a minimum.
