How to add/replace psobject

I am trying to write a script about the state of the server hardware

The following functions have been completed.

Get-SummaryStatus.ps1

Get-Memory.ps1

Get-PowerSupply.ps1

Get-Proecssor.ps1

Get-Fanstatus.ps1

Get-SummaryStatus.ps1 output is

Duo to I have more than 1000 services that need to be monitored, So I want to make the following steps to improve efficiency.

I created a new main function（ServerHealthCheck） and call all sub-founcitons(summary,memory,power...) to main function. (completed)

If the summary state are OK, and then output summarystatus. (completed.)

If Summary memory status is failed. and then will call Get-Memory.ps1 to find which memory is bad.(completed)

If Summary power status is failed. and then will call Get-powersupply.ps1 to find which powersupply is bad.(completed.)

if One of the hardware was failed , I want to rearrange a new object.

my question is How to add/replace object to get expected output? thanks in advance.

Expected output(if summary memory status is failed):
