Hi Mikey54,

This is a good question. I think it's totally fair to switch your 3rd finger (ring finger) and your 4th finger (pinky) on the fretboard in this case.

But if you're doing this solely based on the fact that your ring finger is supporting the little finger, then I definitely recommend you adjust your hand position so that your pinky is able to grab frets easier. Also keep in mind that your pinky will always be a little weaker when holding frets since it can feel awkward using it in this way if you're new to guitar.

But all in all, it should be fine! The thing is to stay consistent, since the F barre shape is moveable and is used for so many other chords.
