I don't like it, because it's less useful than the current default order, which I believe was carefully designed.
This is the current default column order:

Thread | Starred | Attachments | Subject                  | Read | Correspondents | Junk Status | Date
--------|----------|----------------|--------------------|-------|------------------|--------------|----------------------

Rationale of column order wrt proposed changes:
Columns are ordered so as to allow for a fast and intuitive message handling workflow:
- easily identify messages with attachments (attachment column in front). That's important, and attachments are associated with message subject (current order), not with correspondents (so that wouldn't look like an intuitive order to me).
- after reading subject (at least) --> mark read. Imo that's slightly more natural in terms of direction than having to go back to the start of subject to mark read after reading it. Read column isn't very important except for toggling the status, because non-bold is the stronger indicator for read, so read column doesn't deserve front position where it would just distract.
- after checking (subject and) correspondent --> mark spam, because most spams are associated with unknown senders.
- having Starred and Read next to each other isn't a good idea because that makes both of them easier to miss, which is error-prone.
- current spread distribution of clickable small icon columns
  - allows for muscle memory to associate function of column with its position
  - easily identify column status (as opposed to bundling different small columns together)
  - avoid mis-clicks (ux-error-prevention).

Unless there are compelling advantages of changing the existing default column order, I wouldn't touch it. No complaints so far (not a good argument, but still true), and users can always customize. Any changes should explain their rationale, because this is a very exposed and sensitive area.
