Yes you can use stud mount diodes.
Disadvantages:-
You need to use two insulated heat sinks, one for the positive line and one for the negative. If you use all the same type of diode you will need one heatsink for 3 diodes and the other 3 will need their individual sinks ( all insulated)
Advantages:-
Standard units designed for heavy industrial use, more robust, better methods of connection, heat is conducted directly to the sink without an intermediate insulating layer. You can choose diodes of sufficient rating without the questionable issues of parallel devices.
May be cheaper solution once you get over 50A.
