How many posts are we talking here?

Whilst your proposed selection would work, it does sound like a lot of  
processing to ensure that the terms are kept in sync..

My method would be:
Generate tag cloud
  - Are we on a category view?
   - No: Generate as normal
   - Yes: Filter the terms:
    - We want Tags which are attached to <list of posts in category>

You'd have to add some caching to that, and theres a good chance you'd  
have to filter some SQL there for best performance.
I've done something similar (intersections of terms) for navigational  
elements of a custom taxonomy, ie. Site has multiple sections, and a set  
of navigational elements to drill down, In the drill down, you only want  
elements selectable which the section of the site has available
