As the main switches i opted for an BSC110N06NS3GATMA1 from infineon
60V VDS max, 30A seems promising enough. Also my plan is to cool if on the bottom side of the PCB and those things have a massive drain-pad. 10mOhm and 50W loss max should be enough to play with. We will see.
Qg ~ 80nC, ton ~60ns
-> Idrv ~ (80/60)x2 = 2A
-> Rg = 6Ohm @12V
Note: you can always change the gate resistance if necessary

Also from infineon the driver: 2EDL8033F5BXUMA1
This one can deliver 3A, so it should be OK with the max 2A.
Boot capacitance is said to be 10x input capacitance
-> Cboot = 10x1,5nF = 15nF
-> Opted for 470nF for easier supply

Current shunt is a 10mOhm/3W type
Simply because i somehow have a reel of those things .....
15A max -> 2,24W max .... yeah should be ok. 15A is an absolute max anyway ... will be more around 10A so it´ll be fine
