That sounds like a reasonable plan, yes.
An alternative is to change self-insert-command so that it pays
attention to delete-selection-mode (and provides some hook for
electric-pair-mode to indicate when it would use the region).

Yes.

PS: I don't much like delete-selection-mode because of its implementation
strategy (using a pre-command-hook along with symbol properties, as
opposed to modifying the commands themselves). I can fully understand
why it was done this way, but I'd be happy to see it changed, along the
same lines as what we did for the shift-select-mode.
AFAICT, of the various `delete-selection' properties, `kill' is only
used for `open-line' (for no good reason) and could be eliminated.
`supersede' is only used by command which should obey
`delete-active-region' or close enough, `yank' is only used for commands
which end up calling `yank' (so adding code to the `yank' command would
cover them), and t is used for commands which end up calling
`self-insert-command' (with a few minor exceptions like open-line).
