just a doubt regarding 74hc165 shift register and their pins

[BittuCNGT]

i have a throttle planned for which i will be using freejoy with bluepill and it has many input buttons like normal push buttons, 2 way on-on toggles, 3 way on-off-on toggles, multiple 4 way hats with push button function, multiple ky 040 encoder modules will be connected to shift registers, 7 axis (2 for normal throttle using ss49e, 2 for analogue ministick & 3 for 10k ohms potentiometers)

i have already tested a chain of 4 shift registers on bluepill using freejoy.

here is the number of buttons and how i want them and will it work

1. 4 shift registers connected in chain and use B7, B8 pins for ShiftReg_CLK & ShiftReg_LATCH respectively and B6 as ShiftReg_DATA for this chain
2. 4 more shift registers in chain for right throttle handle using same B7, B8 pins for ShiftReg_CLK & ShiftReg_LATCH respectively and C13 pin for ShiftReg_DATA of this chain.
3. 4 more shift registers in chain for button box expansion which i will attach directly to the present setup using same B7, B8 pins for ShiftReg_CLK & ShiftReg_LATCH respectively and C14 pin for ShiftReg_DATA of this chain.
   4, 4 more shift registers in chain as an extra precautionary chain if any of the above registers fail using same B7, B8 pins for ShiftReg_CLK & ShiftReg_LATCH respectively and C15 pin for ShiftReg_DATA of this chain.

will this work or should i used separate ShiftReg_CLK & ShiftReg_LATCH pins for each chain?
