If we put the Stukas in place of the D3A1* at Coral Sea, then we should probably replace the IJN's 250 kg bombs with German 500 kg bombs (the carriers were close but the Stukas probably wouldn't be able to get the 1000 kg bombs that hit Formidable off a deck). If (OK very uncertain) the bombs ended up on the same trajectories, we wouldn't see Yorktown at Midway. In fact, if the bomb that hit actually entered the forward engine room before exploding, it is possible the Yorktown might not have been able to break contact.
* Yes I realise that replacing Dauntless' was suggested.
