That's fine. In your case, if you do buy a book somewhere else as an EPUB, I'd actually recommend to import it into calibre, and then convert it to AZW3. Then export the original EPUB (un-DRM-ed by Alf) and stash it somewhere outside of Calibre. Then remove the EPUB from the library.
If you actually need an EPUB later, then convert that AZW3 again.
Maybe you're doing this already; it might seem a round-about way, but it ensures that all of your books start from the same format, wherever they may go.

In this case I did convert from Original AZW3 to EPUB - then let the extended driver do it's work to convert from EPUB to KEPUB when pushing the ebook to the Aura One.
Would this cause a problem? It was my understanding that the extended driver only works with EPUB, so I had to first convert from AZW3 to EPUB.

It's fine; it's the way you should be doing it.

Is there a reason you prefer EPUB as your base format? Will there be a problem for me if I use AZW3 as my base format?

I prefer EPUB for two reasons:
1. I get most of my books at Kobo
2. I make extensive use of plugins such as EPUBSplit, EPUBMerge, and Modify EPUB, to either split omnibuses, merge short stories of an author into a single book, and to clean up EPUBs before editing them with the editor.
If you don't do a lot of tinkering/fixing with your books using EPUB-only plugins, AZW3 as base format is fine. It is well known, and Calibre can convert perfectly from it, and to it. It also supports all, or most of the markup that EPUB does. If I understand correctly, EPUB and AZW3 are actually quite similar, technically.
Don't switch to KEPUB as your base format. It is not yet as well known or documented as EPUB and AZW3.

AFAIK, not much, if anything. You mostly gain:
- The chapter progress graph
- Chapter time to read
- Next chapter time to read
- Complete book time to read
- Quicker page turns
- A more balanced page if you use headers and footers (IMHO)
The one drawback I can think of is:
- Pagenumbers are not the same as for EPUBs. When using EPUBs, you can use the Adobe algorithm in Count Pages in calibre. Then Calibre and the reader will show the same page numbers. (The Kindle can show any page number scheme you choose, as calibre sends the scheme along to the reader.) With KEPUB, I haven't found a way to match page numbers in Count Pages to the ones used by KEPUB.
If there's a way, I'd like to know
