Hi Yeri

First don't try to solve misalignment problem like this. you need to use first support close to pump as adjustable support to make it properly align.
The exercise you are doing is quite good. It will give you feelings how piping system behave under different condition. Input same displacement values with different type of suction pipe routing & compare result. Then you can get good idea about piping behave under different situation that eventually help you to solve practical stress problems.
Good luck.
