For all such specific purposes, I implemented Lua scripting...
You may simply add the GetOutfitStats() function to your automation.lua script and bind it to either a Lua pie menu slice, a Lua side-bar button, or use it in an OnSendChat() callback, associating it for example to an "/os" (for outfit stats) pseudo-gesture. And of course, instead of printing the report in the chat console, you may use a Lua notification... Example:
EDIT (2020-11-21): added today's viewer release attachments limit support (via GetAgentInfo()) in GetOutfitStats().
