I’m playing around with the idea to use a nested layout with a couple of chunk-based form elements (input text, etc) as simple form builder.
Not sure about caching an render hierarchy though.
Is it worth following this road, or should I avoid that rabbit hole?

It is definitely a rabbit hole, but it’s up to you if you want to dive into it. 
There’s this, but it hasn’t been updated in a while.
We successfully used CB with Formit to provide users with form builder, including single and two-column form layout, text fields, textareas, radio groups, checkbox groups, file upload fields, dropdowns, email notifications, autoresponders etc. Initial setup is quite complicated, you need to understand quite well CB, Formit and MODX itself. But in the end of the day, customer is happy
I was also dabbling with that idea some time ago, but then decided to extend my contact-form-element to a “Multi-Purpose” Contact-Form, which is a “very light” Form-Builder:
The editor can choose which fields should be activated, and which fields should be required (via “Multi Select Fields”):
Inside the FormIt-configuration, I set them something like this:
Maybe someone finds that inspiring 
Considerung that a full fledged form builder will be overkill for many end-users, your solutionis is nailing it! Thanky for sharing.
You’re very welcome - I wish you a lot of fun 
If you encounter any problems, or want to share some neat tricks, I’m looking to reading back from you
