You would want a higher pitched switch if you want to achieve a similar sound.
Something like a gat milky top yellow on an aluminium plate could work for the board, they are pretty good switches when modded properly (spring swap to something consistent, breaking in and lubing) and they have a pretty high pitch sound. Maybe use a thinner lube like 3204 which makes the switch less deep than 205, and still makes switches smooth.
gat x on alu is also nice and you don't really need to break in the switch, just make sure you spring swap and lube with an oil like 105g0 (this would be more higher pitch from experience) but it is more expensive.
also sure you remove the foam that I believe comes with the M1 as that usually deepens it as well.
