Using PowerShell Functions in t-SQL scripts

Question

experts,
Can I use a power shell function that gets file size given file path by cross applying it to a table in SQL Server that holds file path of files?
fileID    filepath
1         L:\DemoWebPages\About.cshtml.txt
2         L:\DemoWebPages\default.cshtml.txt.txt
3         L:\DemoWebPages\Layout.cshtml.txt
4         L:\DemoWebPages\Site.css.txt
if the above if the table in SQL Server, can I cross apply a power shell function that gets the file size when file path is passed from the table above?
Help Much Appreciated!

Make sure that you are running on the machine where you've full permission to access file and 
Sample data
create table filelist
fileid int,
path varchar(200))
insert into filelist values(1,'c:\Demystifying tempdb whitepaper.pdf')
insert into filelist values(2,'C:\Appleton Papers - 23 SQL DM - dani 6.28.13.pdf')
Powershell Scripts:-
Add-PSSnapin SqlServerProviderSnapin100 -ErrorAction silentlycontinue
Add-PSSnapin SqlServerCmdletSnapin100 -ErrorAction silentlycontinue
Function filesize
param([String] $path)
try {
if(Test-Path $path)
$size=(Get-Item $path).length/1024
write-host "$path size is $size KB"
catch [System.Exception] {
write-host "File not found"
$params = @{server='hqvd0026\kat';database='master'}
$Srv = invoke-sqlcmd @params -Query "SELECT * from dbo.filelist"
$srv
foreach ($db in $Srv)
filesize -path $db.path
