In this fanfiction, Gohan's life could take a more academic turn. Since he doesn't meet Veal, he may be more focused on his studies. He could become a renowned scholar in the Saiyan - Earthling community, researching about the history and potential of both races. His knowledge could then be used to develop new technologies or ways to defend the Earth that don't rely on brute strength but rather on intelligence and innovation.
Gohan might be more introverted. Meeting Veal could have been a factor in making Gohan more social in the original story. Without that encounter, he could remain more of a loner, concentrating solely on his own growth, whether it be in terms of power or knowledge.
In this fanfiction, it could start with Gohan exploring an ancient Saiyan relic. Unbeknownst to him, this relic has the ability to bring back the spirit of Bardock. Once Bardock appears, he is initially confused about where he is and who Gohan is. Gohan, being the kind - hearted person he is, explains the situation. As time passes, Bardock starts to train Gohan, pushing him to new limits. Gohan also shares his knowledge of Earth's culture and values with Bardock, which makes Bardock see a different side of life compared to the brutal Saiyan culture he knew. This interaction could change both of their perspectives and lead to a new understanding between the past and present of the Saiyan race.
In the 'Gohan meets Bardock' fanfiction, it might start with Gohan stumbling upon an ancient Saiyan relic that somehow connects him to Bardock. Bardock then appears as a spirit or through some time - traveling magic. They have a deep conversation about the purpose of the Saiyan race. Bardock could be proud of Gohan for breaking the mold of the typical Saiyan, being more about protecting the innocent rather than just fighting for power. Gohan, in turn, could be inspired by Bardock's raw Saiyan spirit and find a new way to combine it with his own values.
Perhaps Gohan meets Zeno during a multiverse tournament. Gohan, being the smart and powerful warrior he is, could start a conversation with Zeno about the importance of protecting all universes, not just for the sake of power but for the life forms in them. Zeno might be intrigued and start to see the universes in a new light.
The plot could also focus on their relationship. Since they are brothers but from different timelines in a way. They could bond over family stories that Goten has heard but Gohan can now give a different perspective on, like stories about their father. And they might train together to become even stronger for the future battles that Gohan foresees.
One possible plot could be that future Gohan travels back in time to warn the past about an upcoming threat that was not properly dealt with in his own timeline.

Maybe he also meets the past versions of his friends and family, and has to convince them of the seriousness of the situation without revealing too much about the dark future he comes from.
One possible plot could be Goku reminiscing about his past with Grandpa Gohan. Maybe he visits the place where they used to train together.
