No...it would require one more licence were you to purchase Object Desktop.
Were you to purchase another licence for each individual program, then add up the cost of each additional individual licence.
Remember: The best deal is with Object desktop in terms of the number of programs you're subscribing to.
If, however, you want only Windowblinds, Fences and Cursorfx, I'd ask you if you're on Windows 11, because Windowblinds 11 requires Start 11 to skin the Start Menu correctly...so you'd have to buy Start 11 for whatever number of W11 machines you are going to customize.
I'm not a Support/Sales person so I might be mistaken. I'd suggest waiting for a Community Support Assistant to answer before making a decision.
Happy holidays and happy customizing to you!
