Arduino Mega & A4988 Driver Module

Both my 3D Printers run with a dual Z in parallel now for 3 years with no problems.
Do not like the ideal of twice the current though, if I designed the circuit would had wired them in series.

I have been thinking about my MPCNC it used X & E0 for X and Y & E1 for Y to drive stepper motors.
I want to change this and leave the E0 & E1 for Other purposes.

I have two ideals

1st - Can I wire two Stepper Motor modules to the same pins leaving the 4 pins connections to each Stepper motor separate.
This way I would have a separate Stepper motor module for each stepper motor and reversing JP3 connections would reverse the stepper direction.



Attached is an A4988 Driver module If connections were made to both drivers exactly the same on JP4.
Could I wire the two JP3 connections too two separate Stepper motors & even be able to reverse the connections to reverse the direction of turn, or will this overload the Arduino Mega 2560.

2nd - Wire the Stepper motors is series or parallel with a single stepper motor Driver module.
