Mi	Sol	Fa	Sol
Sol	Sol	La	Ti
Do	Re	Do	Re
Do	Ti	La	Sol
I	V⁶	IV⁶	V

Yes in this case V can go to IV!!!

When you have successive first inversion triads the voice leading works well when a different part of the triad is doubled
Very effective is alternating doubling the root and the third

Do	Do	Re	Ti	Do
Sol	Sol	La	Sol	Sol
Mi	Mi	Re	Re	Mi
Do	Mi	Fa	Sol	Do
I	I⁶	ii⁶	V	I

Doubled the third then the root

Do	Do	La	Ti	Do
Sol	Sol	La	Sol	Sol
Mi	Do	Re	Re	Mi
Do	Mi	Fa	Sol	Do
I	I⁶	ii⁶	V	I

Doubled the root then the fifth

Do	Do	Re	Ti	Do
Sol	Sol	La	Sol	Sol
Mi	Sol	Fa	Re	Mi
Do	Mi	Fa	Sol	Do
I	I⁶	ii⁶	V	I

Doubled the fifth then the third
