I do like the ideas for the additional 30amp power cord. Didn't think of that and it makes sense to do that instead of the 12 or 10 gauge cord.
Yes, you'll simply swap out the 40 amp breaker for a 30 and use the available space in the box to feed your outlet. Depending on where the 40 amp pool circuit ran to, you might
be able to utilize that wiring to feed your outlet box as well.
EDIT: Just be sure your 30 amp outlet gets wired to 110v!!
Many get into trouble when they mistakenly wire it at 220v like some older home, 30 amp dryer/range outlets were.
