How Do I run Powershell x86 from Powershell?

The core structure including passing of parameters in either scenario is given below

Param(
    [String] $Param1 =@("Param1"),
    [String] $Param2 =@("Param2")
)
    $ScriptLocation = Split-Path $script:MyInvocation.MyCommand.Path -Parent
    Write-Host $ScriptLocation

$RunAs32Bit = {
    Param(
    [String] $Param1 =@("Param1"),
    [String] $Param2 =@("Param2")
    )
    ...        

    return $Result  
}

#Run the code in 32bit mode if PowerShell isn't already running in 32bit mode
If($env:PROCESSOR_ARCHITECTURE -ne "x86"){
    Write-Warning "Non-32bit architecture detected, processing original request in separate 32bit process."
    $Job = Start-Job $RunAs32Bit -RunAs32 -ArgumentList ($Param1, $Param2, $ScriptLocation)
    $Result = $Job | Wait-Job | Receive-Job
}Else{
    $Result = Invoke-Command -ScriptBlock $RunAs32Bit -ArgumentList ($Param1, $Param2, $ScriptLocation)
}
