Had the convoy not scattered perhaps the Germans would have thought the risks worth it.
No way.....the Germans knew they had the Air Power and U-Boats arrayed to do the job with no risk of losing their very limited Surface fleet units in a sea battle with Allied Surface Units that included an Aircraft Carrier.
They had learned the lesson about what threat enemy aircraft could be.
Unlike the British who sent two fine ships to a certain death early on in the War during the fight for Singapore.
Now if they could have coordinated an Air/Sea attack.....perhaps they might have thought about it.....but they probably had not progressed to that ability owing to the distances involved and the questionable weather.
The Tirpitz did far more good at anchor as a potential threat than at sea engaging numerically superior Allied Naval Units with far less risk of loss.
