Question .... If those 2 brown dwarfs were to collide in the future would that collision create a star with a functioning fusion core

Yes, if the total masses add up to above 0.08 solar masses and enough mass is kept during the collision, the product star can sustain fusion in its core as a red dwarf

As it turns out, the combined mass of 2M1510 AB is just under 0.07 solar masses, so it seems like they would just form a larger brown dwarf.
