Don't think so

Good distortion performance for a single 211 or 845 requires a primary Z at least 10KΩ. And flat response to 20Hz at full power (say 30W in A2) would require a much larger core than the 1642SE if DC is flowing. I think it might not even be possible to accomplish both criteria (10K primary and much larger core) while also maintaining flat response to 20kHz. This is the weak link in SE amps at power levels above 12W or 15W.
