I'm all for it... a well established prefix for 1/1,000,000 would be 'micro'. So, we could use 1 micro-bitcoin = 100 sats, for example.

I think 1,000 sats = 1 bit would work nicely You just move the decimal 5 places left

BTC to Satoshi to USD

That was argued over years ago, people tried bits and millibits and it just confused everyone. What didn't confuse everyone was Bitcoins and Satoshis.
