In-kind conversion to FBTC / FETH

It would be cool if balances in a crypto account could be exchanged in-kind for Fidelity ETP shares if the holder elects. This would among other things open up the ability to get yield on FETH but would also let people benefit from SIPC protection for securities, etc. If individual investors are too small to do this for, conversion requests could be aggregated at periodic intervals. Is that something Fidelity could consider?
