ok so my s8 had a cracked scree kid dropped it down the toilet and bingo phones dead so my question is if i order another s8 with a cracked digitizer can i use the digitizer which is not cracked from the water damaged s8 as a replacement

In theory yes, in practice i wouldn’t unless i can ensure no corrosion damage to connection terminals. Depending on your cost might be worth it to test. New screens and digitizers I’ve seen are ranging from 50 (dont trust) to 200. So you always have another option.
