How can I modify various settings inside either a new or exisitng App Pool using Powershell?

I am interesting in some of the "Advanced" settings such as Enable 32-Bit Applications, Managed Pipeline Mode, Process Model Identity, etc. Any ideas on how I can do this? I tried using the xWebAdministration module but that seems to have very basic settings.

Yes, a custom DSC resource is the only way to do this with DSC. If you are able to use PowerShell scripting without DSC, you can use the WebAdministration module module to create the pool, and then modify it from there. 

$appPoolName = "MyAppPool"
New-WebAppPool -Name $appPoolName
$appPool = Get-Item "IIS:\AppPools\$appPoolName"
$appPool.processModel.identityType = 3
$appPool.processModel.username = "someUser"
$appPool.processModel.password = "somePassword"
$appPool.managedRuntimeVersion = "v4.0"
$appPool.managedPipeLineMode = "Integrated"

Update 1/31/2015

In the PowerShell.org community DSC modules, someone made a cWebAdministration pull request that apparently includes "37 app pool config options". Might be a great solution.
