Or would there be a sacrifice in sound?
The sound is the same, except for any noise made by the release of the key. Try it for yourself and see (that is, hear).
True, but only if you hold the pedal all through the bar. I don't think I'd want to, with so many densely packed 6ths to fill up the sound.
The best fingering would depend heavily on the next bar, as I suspect that the music would call for a strong sense of connection to whatever begins the following bar, rather than a self-contained unit that ends at the barline. However, 52-41-52-41 (connecting the 1 to the 2 with full legato, on the 14-25) would probably work, if you have a large enough hand.
If you do repeat the thumb, the key is simply to rest properly upon the keybed before release. Students I've had always worry too soon about the following note, in these kinds of passages. Just play the first 6th as though nothing follows- ie relax straight down. You need to feel a true sense of resting here. It's common either to fail to feel the bottom of the keys in the first place, or to continue pushing at the keys with unnecessary muscular effort, rather than find balanced alignment. After resting properly, release the thumb as a completely separate process and move it over the following note (but retain the weight FULLY on the upper finger). Then you can fully connect with legato, to the following fingers. This may seem extremely indirect, but before you isolate these individual components of the whole, you cannot hope to put them together as a more rapid movement.
I'm not sure whether Alan would say similar things or not, but from my experience, the key is essentially to train your hand to reach a neutral, balanced position on EVERY 6th (firstly with the thumb down, and then after the thumb has been released). Even when done at speed, there should be a fractional moment of balanced comfort, between the key strikes. The flaws usually comes through the unwanted tension of anticipation- which can manifest itself as excessive pushing after the key has been depressed or failure to get fully into the base of the keys in the first place. Concentrate on the intermediate points of weighted balance, to remove either problem.
EDIT- one other thing: I'd lift the thumb high in between the two notes and gradually reduce that bit by bit. It's easy to try and make the movement TOO concise too soon, before having learned to control the relevant muscles. Remember that 'jabbing' the thumb is the worst thing. Counteract any tendencies towards this by using big swinging movements of the thumb (feeling the aid of gravity upon a vertical descent, rather than the muscular tension associated with a locked 'jab'), before you try to reduce this to anything that is remotely concise. Eventually you will find that it's possible to keep the same 'feel' of the movement, while gradually reducing the distance travelled. I'm not personally convinced about the 'glissando' (at least not in the same sense as when you run your thumb nail down the sides of a series of keys), but as the movement becomes more efficient, it can eventually be done legato. The freedom of movement must be the starting point though! If you aim for true legato too soon, you'll probably fall into the trap of jabbing your thumb.
