That particular alias command (as you discovered) will not work because the
'script' command takes raw input, so the % arguments do not get interpreted as
place-holders but as part of the raw input text.
You could try something like:
_GetDebugger().HandleCommand("commands alias showimage script
ImageData.ShowImageARGB")
(lldb) showimage (300, 200, "myStruct->mImageData")
I believe this will work. (It worked in my test case).

There are definitely plans to eventually add the ability to register your own
commands more like built-in commands (it's been on my to-do list for a while),
but I'm not sure when we will get around to implementing that.

If you need/want any more help with any of this stuff, please let me know; I
will be more than happy to help you.
