Extending the vanilla Revit shortcut key capability

I don't normally post "paid" addins, but this is an interesting little idea for an app:
Assign a HotKey to a specific component, not just a command (link)

I wonder if someone would like to make a Revit add-in that allows mapping of a multi-step command to one hotkey?  Here's what I'm basically thinking:

• separate hotkeys that can launch different New Family commands using the different Family Templates for each category (ie. a shortcut for New Generic Model Face Based etc)
• ability to string multiple standard Revit keyboard shortcuts together with other keyboard methods, so that you could accomplish something like this or even this with just one keyboard shortcut
