I've talked with Lambo execs about this at last years ROTB and Concorso.
They know about it. They have ideas.

But the cars you mentioned are significantly more expensive than a Murci.
This is a known problem with CF.

Audi has expertise with aluminum. Ferrari used CF for the Enzo (target
was a limited run and higher price), but uses aluminum (through affiliation
with Alcoa) for their other more inexpensive, produced in higher volumes,
street cars. Carrera GT produced almost 1300 cars, but they're more
expensive. Zonda is real small production and higher price

Nothing is stopping you from developing a CF Murci chassis yourself and
attaching parts on it from an older Murci. I suspect you may want to look
at lighter engine components as well. I'm looking forward to it ! Please go
to ALMS and kick those C6R's butts!
