Convert String and set as displayname for mailbox in bulk

Question

Hi All,
Need a favor to convert the existing displaynames to right format and then set the displayname for bulk mailboxes.
Current Displayname - "Ranji Rock MBA\DBA\RISK\FIN"
I need a script to convert the above text to "Ranji Rock MbaDbaRiskFin" and set it as displayname. Could someone help me to remove those slashs in the text and adding the first letter in caps??
Never giveup till you get what to want.

This should work, or give you a direction to head to, but please test it on a test OU first!!!
$users = Get-ADUser -SearchBase "OU=Users,OU=To,OU=Path,DC=Here,DC=Company,DC=your" -Filter * | select sAMAccountName, Name, Displayname, 
ForEach ($User in Users){
$ExistingDisplayName = $User.Displayname
$Newdisplayname = $ExistingDisplayName -replace "\\","" #Need the \\ as \ is an escape Charactor
Set-ADUser -Identity $User.sAMAccountName -Displayname $Newdisplayname

Adam - the OP is looking to rename the displayname of mailboxes, not the AD accounts.
