Tube amps, let's see where can we place the output tubes?

Wrong again, grasshopper!
The magnetic field strength outside the iron core is not strong enough to influence the tube operation. The iron core is designed to contain and concentrate it.
Most amplifiers have the power tubes relatively close to the output transformers.
Check out the Audio Research VSi60, for example. The power tubes are right next to the transformers. Duhhhh. They have been engineering and manufacturing the best of the best in tube amps for 40 years. Maybe they have thought about these things more than you, do ya think??
Very funny. You must not have received the memo. there is a monster magnetic field and that field extends to almost every element of the amplifier. don't feel too bad, the manufacturers didn't get the memo, either.
Oh, I almost forgot, the rectifier tubes are also right in the line of fire.

Congratulations; you have just revealed why every tube amplifier made in the last 70 years sounds so bad; those damn magnetic fields!
Greetings from planet earth.
Obviously you haven't experimented with mu metal. That's the differenrece between guessing at something and knowing. Unfortunately the induced magnetic field is everywhere, interconnects, power cords, speaker crossovers, speaker magnet assemblies, yadda, yadda.. Think of it as shooting yourself in the foot.
