I could try, but I think "engine cooling and baffeling" is specifically
spelled out as a major alteration in the AC of 337 instructions. The ram
air source for the shroud would require a hole through the rear baffles.

Most Piper small singles (PA28's) have exactly such a cooling shroud
around their mechanical fuel pumps. Perhaps you could talk you A&P into
installing them on your Aztec as a minor alteration?
