You can actually play a landless characer

Many mods already use this, AGOT uses it for Dany and Jon as well as a few others. They have done so for many many patches.

Don't make them titular county tier titles though as you cannot destroy them as counties are meant to always tie to a province on the map so there are safe guards against count titles being destroyed. Make your titular titles duchy or above as they can be freely destroyed, recreated and fully deactivated.

Just use duke or above titular titles, it is more work for me to go in and find every reference to a count title and whether it being landless or not is important than it is for you to change c_ to d_. And on the grounds it being count or duke is not important there are other modding things I think my time would be better spent on
