I was thinking about what you propose. I do not understand why a simple extension is not better.

I do not understand why we should involved Smalltalk

it can be different class playing as access point to tools registry. why its better - because your code does not rely on specific classes, which can be missing in image. The idead is, that to get a service (or tool) you need to send a message, without referring to specific class(es). Then any installed packages may add/remove/replace entries in registry and can be used directly by your code without any specific knownledge about who or what is standing behind it.

...

you write

Smalltalk tools UIManager

instead of UIManager default

or Smalltalk tools browser

instead of SystemBrowser default

it would be nice to see similar in UIManager, e.g.

manager registerTool: #colorPicker class: MyCoolColorPicker.

and then simply use:

manager colorPicker new openInWorl

I do not understand the gain of your approach.
