Custom List Form creation using Powershell - SharePoint 2013

Question

I have a custom List called 'IssuesList' with 4 fields - "IssueTitle","IssueID","IssueDesc","Status"

While displaying display form I should show 3 fields expect Issue ID i.e. IssueID should be hidden.

and on edit form only Status field should be editable. So using SharePoint designer I created respective Edit form and display forms and changed XSLT to control the display mode on the fields.

I have everything scripted in powershell till now - creation of custom list, publishing pages, webparts etc. however I am looking for how to provision or associate these 2 list forms with IssuesList after I create the list in new site.

I have restrictions on using wsp and site/list template due to business needs. So I need to know if there is any way I can upload these 2 files after I create custom list in powershell and associate them as defaultdisplay and defauteditforms?

Please advise

Here is one script which I use often

$url = "Enter URL" 

$listname = Read-Host "Enter List Name"
$web = get-spweb $url 
$list = $web.lists[$listname]

#delete existing forms

$files = $list.rootfolder.files
$form1 = $list.RootFolder.files | ?{$_.url -match "dispform.aspx"}
$form2 = $list.RootFolder.files | ?{$_.url -match "editform.aspx"}
$form3 = $list.RootFolder.files | ?{$_.url -match "newform.aspx"}
$form2.delete()
$form1.delete()
$form3.delete()
$list.update()

#Upload new forms
#$dispform = $files.add($dispformurl, [Microsoft.SharePoint.SPTemplateFileType]::FormPage)
#$editform = $files.add($editformurl, [Microsoft.SharePoint.SPTemplateFileType]::FormPage)
#$newform = $files.add($newformurl, [Microsoft.SharePoint.SPTemplateFileType]::FormPage)

#Set new form urls
#$editformurl = $list.RootFolder.ServerRelativeUrl + "/editform.aspx"
#$dispformurl = $list.RootFolder.ServerRelativeUrl + "/Dispform.aspx"
#$newformurl = $list.RootFolder.ServerRelativeUrl + "/NewForm.aspx"

#set new form association
$list.DefaultDisplayFormUrl = $dispformurl
$list.DefaultEditFormUrl = $editformurl 
$list.DefaultNewFormUrl = $newformurl

$list.update()
