To a certain extent, it was possible!
As long as Xia Qing agreed to give up young Gohan's body and spend one wish, Porunga could transform him into a constitution similar to Majin Buu's.
Porunga could even easily create a complete copy of Majin Buu's soulless body and fuse Xia Qing's transmigrator soul from within young Gohan into it.
However, Xia Qing's ambitions were too great.
He was unwilling to give up the terrifying potential of young Gohan's body, yet he also wanted Majin Buu's Super Cell Regeneration. What could Porunga do? It could only say it was powerless.
"Hahaha, interesting!"
"Porunga of Namek has actually learned to play word games!"
Above time and space, Baros smiled.
That transmigrator's thinking was far too taken for granted. He single-mindedly pursued Majin Buu's Super Cell Regeneration, wanting to ascend to the heavens in a single step and crank his cheat abilities to the maximum.
If he had calmed down and asked a few more times, without demanding complete Super Cell Regeneration.
If he had only asked for half, or even just part, of Majin Buu's Super Cell Regeneration.
Then his wish could still have been granted.
Unfortunately, this transmigrator's patience was truly lacking.
After Porunga stated that it was powerless, he gave up this opportunity to rapidly grow stronger with barely any hesitation and instead voiced the wish he considered second only to Majin Buu's immortality.
To obtain Broly's Legendary Super Saiyan Bloodline.
Then, without question, he failed again.
Broly across every timeline in this time and space of the Dragon Ball Super Universe had been erased by Baros before he took him away, when Baros first descended back then.
He existed neither in the past nor the present.
Only in the future, during the era of the Tournament of Power.
