Actually, I recommend you forget trying to duplicate Bonham's sound with drums that are nowhere near his sizes and instead find out where your drums with your head selection want to be tuned to sound their best.
That means putting each tom into its most resonant range, so each is at its loudest and sustain is equal from every drum.
Put the DD on the shelf for a while and do this with every tom:
Take both heads down to finger-tight. Add no more than 1/4 turn to each tension rod, top and bottom, using two keys on opposite tension rods and using a star-pattern. If the drum is still flappy add 1/4 turn more. Keep adding 1/4 turns all around until the drum plays a real note. At this point make both the top and bottom heads the same pitch and touch up the lug-to-lug tuning.
You have just found the lowest note that tom will play.
Now add 1/4 turn at a time to all tension rods, keeping the pitch the same and keeping the lug-to-lug tuning decent. Strike the batter in the center of the head after every round of tension.
Eventually you will reach a place where the drum is louder, punchier, and has the most sustain. That's your sweet spot. Above this pitch the drum begins to choke. Once it's well-tuned in the sweet spot, now you can take out your drum dial and measure what you have. Don't be surprised if you have varying readings from lug-to-lug, drum dials do that. (Your ear is better at fine tuning.) Take an average and make a note of it so you can find it again.
Do this with all your toms. At this point they should all be relatively equal in loudness and sustain. If that's too much sustain for you, now is when you can fool around with raising the reso relative to the batter to cut sustain. Bonham used to tune his resos way higher than the batters, as much as a fourth or a fifth. That works on big drums, it may be too much for yours.
Finally, Bonham used (on his wooden drums) coated Emperors over coated Ambassadors on his toms, a coated Emperor snare batter, and coated Emperor batter and reso on his bass drum, with felt strips for muffling. You can try these, or perhaps the Vintage Emperors. My kid played on a backline kit with them and they sounded very Bonham-y.
