Absolutely possible with PowerCLI.
This is probably incomplete from what you want, but should get you started:
$VMs = @("VM1", "VM2")
$Report = ""
foreach ($VMin$VMs)
{
$Report += "<h1>$VM</h1>"
$Report += Get-Stat -Entity (Get-VM $VM) -Start (Get-Date -Hour 8 -Minute 0 -Second 0).AddDays(-1) -Finish (get-date -Hour 18 -Minute 0 -Second 0).AddDays(-1) -Stat @("cpu.usage.average","mem.usage.average","cpu.ready.summation","disk.maxTotalLatency.latest","disk.usage.average") | Group-Object MetricID | Select Name, @{Name="Average";e={($_.Group | Measure-object -Average Value).Average}}, @{Name="Unit";e={$_.Group | Select -expandproperty Unit -First 1}} | ConvertTo-HTML -Fragment
}
ConvertTo-HTML -Body $Report | Out-File ("{0}\VMreport.html"-f$Env:Temp)
Invoke-Item ("{0}\VMreport.html"-f$Env:Temp)
Just replace the VM1, VM2 array values with your VM names (and add the rest, obviously)
You can run Get-StatType -Entity (Get-VM VMName) where VMName is the name of one of your VMs to get all available metrics.
You can also use the Send-MailMessage cmdlet to send this via email if you wish.
