We did this on a former boat, whether this will work depends on the boat's configuration and the location and slope of the new 'drains'.

In our case unfortunately we ran the drain from aft in the cockpit out under the counter (the actual transom was too high) and we discovered that when heeled the stern wave caused water to backflood into the cockpit where previously it had not with the thru hull drains. In retrospect crossing the drains over side to side may have solved that one, had there been room to do so.

On another boat I've seen it done, but with poor slope leaving a low spot that stayed full of water - it froze one winter and split open. However since it was all above the waterline the only water that got in the boat was rain water.

Anyhow, the upshot is that while it sounds a great idea, how well it works depends of the relative locations of cockpit floor, transom elevation, hull shape etc.

Maybe get a cutaway profile drawing of your boat and do some sketches first.
