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
