Should use supercharged small displacement V12s. But that would pretty much crush F1 so not happening.
And where would these mythical engines come from, do you think?
Do you know WHY almost every F1 team started using V10 engines in the
early '90s?
Don't reinvent the engine, shouldn't be to hard to make new castings or maybe 3D print them from already tested designs.
You're missing the point:
"Should use supercharged small displacement V12s"
What do you mean by "small displacement"? I'm assuming smaller—perhaps
much smaller—than 3 litres because you want them supercharged.
Only no one has made a small displacement V12 since the 1950s.
What I'm getting at is that engineers have worked out there is an
optimal number of cylinders that varies with displacement. F1 cars went
to V10s because at 3.5 litres, they were more efficient; they turned
more of the fuel burnt into useful torque and lost less to the friction
that a V12 of the same displacement would have had.
So when you start talking about a "small displacement V12", you're
making things needlessly complex for no benefit. If small displacement
using supercharging is the way you want to go, then the correct "V"
engine is probably a V6.

"A decade or so ago, a team of German university scientists settled on
500 cubic centimeters as the ideal per-cylinder displacement for internal-combustion engines. ..."
