Why weren't Crusaders Kingdoms under the Germanic and French crown?

Interestingly imo, at least one of the Crusader states fell under nominal Mongol sovereignty. Bohemond VI of Antioch became a tributary of Hulegu Khan, and I believe Antioch contributed some troops to Mongol campaigns in Syria during the 1260s.

the bit about the Jerusalem crown being offered to the emperor
vague memories but I think it was the Grand Master of the Teutonics Hermann von Salza
who was both the Pope and the emperor good friends good friend ( an impossible combination ) who suggested it

the purpose was to get some solid support for Outremer ,
the Crusading kingdoms didn't have the men or resources to stand on their own against an unified Muslim Near East

anyone can proclaim himself King ,
for the purpose of making matrimonial alliances , a formal status was necessary
in Europe the tittle had to be recognized by both the Pope and the Emperor to be considered first class
to be declared a prince only one of them was enough
