Keeping a Mountainboard build light | First build

Hum i’m not sure if I understand The board has somewhat tip ends and came with these trucks

Should I get longboard trucks (something like caliber II trucks) or some other MTB trucks.
If I keep the current trucks what would be the best motor mounts that fit these?

I saw this pack from Flipsky which seems like a good deal.
They also have a smaller and cheaper pack with 6354 motors.

For the battery, i’m thinking of going with a top case (haha) and 2 or 3 lipos - I have had good experience with Tattu and CNHL lipos with my drones.
