it's not possible becuase it's DIGITAL MIC, not analog one like in previous nokia model. you need to understand what digital means, you can't make some wires, solder from any other model (except compatibile).
it's driven via DMIC signal from rapidyawe so solution for you is easy - find new and solder it, it doesn't cost too much nowadays, or if you can't buy but you have some dead pcb you can use it. which one ? welll. just look :

it's B2100 on schematic, to be clear it has 5149079 code in Nokia, it's compatibile with:

Nokia 3120 Classic RM-364 B2100
Nokia 5310 RM-303 B2150
Nokia 6212 Classic RM-396 B2100
Nokia 6500 Slide RM-240 B2102
Nokia 6650 Fold RM-400 B2201
Nokia 7210 Supernova RM-436 B2150
Nokia 8600 Luna RM-164 B2201
Nokia E51 RM-244 B2100
Nokia E71 RM-346 B2100
Nokia E90 RA-6 B2100

I hope it's a bit more clear for you and other forum members.

have a nice weeekend...
