Fiery-Yes-technically I suppose it was-if you count the Frog Venom and the DC Bee as being simply derivatives of the Wasp (which they are)-and the 1973 Mk2 Rapier as a reintroduction of the 1957 one. The only question mark would be the very very few 1980s era Bambis that were made-there's a photo of one in the Clanford book-was a redesign done? The appearance is different enough to suggest that it might have been-but in any case these didn't go into production (more's the pity!)....
Returning to my earlier comments on the noise aspect-I suppose the sensible experiment would be to run a Bantam and a Wasp and measure the noise levels-some engines ARE intrinsically noisy by dint of their physical design-but whether that applies in this case we'll have to see-the Wasp has generous exhaust port area, the Bantam far less so............
