Replacing rear spud flushometer bowl with top spud

[Bklynchica]

Hi,
My NYC co-op apartment has an American Standard rear spud bowl that has a few issues (with bowl and flushometer). The previous owners renovated 6 years ago, but I don't think they replaced the toilet because I can't find it for sale, and there are stains on the inside bottom of the bowl that no amount of scrubbing removes.

3 times over the last year our super has had to adjust the valve because the flush got too strong and was splashing water all over the toilet seat. He suggested that we need a new valve. Now the toilet leaks from where the pipe attaches to the toilet spud with every flush.

We feel done with this setup. It doesn't match the rest of the really nice bathroom renovation. I don't know the rough in.

I really like this toilet because it would be up against the wall, and has a shorter distance from wall to end of bowl than our current one. I think it's more modern looking. Is it relatively easy to go from a rear spud to top spud? Would the plumber need to make a new hole in the tile or do new piping behind the wall? It has a 12" rough in. Is it possible to use it even if current toilet is a 10"? Could I get any top spud flushometer that I like to go with it? About how long does this type of work take, and what is a fair price? I understand these questions might not be possible to answer. Any insight is appreciated!

The rough-in is measured from the back wall to the center of the drain. The closet bolts are centered on that.
With that measurement, you can take the specs and see how far the valve at the wall may need to be moved. That can involve shutting off water to that column of bathrooms.

Thank you! It's actually a 12" rough in. Does this mean I can safely order the new toilet and any flushometer I like to go with it? Is this a 3 hour type of job, or a full day type of job? We only have the one bathroom. Also thinking of ordering some extra wall tiles. Is that necessary? Thank you so much!
