We sure could use more of this type of endeavor nowadays.
The word however is "Pliotron", not pilotron.
I've seen where several individuals making one-off tubes have success, the money shot will be glass tubes in the 500W plate dissipation class.

Looks like there was a Pilot Tube Company, though I thought the gent said he was recreating a tube that wasn't marketed. Dunno.

Langmuir coined the term 'Pliotron", and it was licensed to GE.
A much improved tube over the original Audion.

Was it used in anything or was it quickly eclipsed?

The tube? Evolved right away.
The name? Lived on in GE industrial tubes till the end of production in the 90's.
