The question is more of will your customers agree to go along with this major architectural shift that sets you back on price-performance-power curves by at least five years and moves you out of the mainstream of board support packages, drivers, and everything else software-wise for phones.
Also we should not pretend that ARM is just going to sit there waiting for RISC-V to catch up.

Embedded is moving to RISC-V where they have low performance needs.
One example is the Espressif line of CPUs - which have shipped over 1B units. They have moved most of their offerings to RISC-V over the last few years and they are very well supported by dev tools: https://www.espressif.com/en/products/socs
