He could collaborate with Ollivander. Ollivander is the expert in wands, and he has a vast knowledge of wand - making materials and techniques. Working together, they could combine their knowledge to create something truly extraordinary.
There's also a chance that he works with a foreign wand - maker. Maybe someone from a different wizarding school or culture who has a completely different approach to wand - making. This would introduce new ideas and materials into the process of creating the new wand.
The new wand might have a core that is a combination of multiple magical elements. For example, a strand of a unicorn's hair combined with a shard of a powerful magical crystal. This would make the wand extremely versatile, able to channel different types of magic depending on how the wizard holds it and the incantation used.
Maybe it's an old wandmaker from a far - off land. This wandmaker has been crafting wands for centuries and has a unique intuition about which wands are meant for which wizards. He sees something special in Harry and presents him with a new wand.
He might choose a phoenix feather because it represents rebirth and magic. And for the wood, perhaps he'd pick holly, which is often associated with protection in the wizarding world.
Maybe he found a really cool and powerful wand that he thought would be better suited for someone else. So he decided to gift it.
One idea could be a wand that chooses an unlikely hero. Maybe a Muggle - born who has a special connection with an ancient and powerful wand that was thought to be lost. The wand could lead the character on a journey to discover hidden magic within themselves and in the wizarding world.
In the 'Harry Potter gets a new wand fanfiction', Harry getting a new wand could lead to a whole new set of adventures. He might have to go through a series of trials to fully bond with the wand.

It could also attract unwanted attention from dark wizards who are jealous of its power.
It could be an old and reclusive wandmaker who has a special connection with Harry. Maybe this wandmaker sees potential in Harry that others don't and decides to create a custom wand for him.
Harry Potter's wand was made of holly wood, with phoenix tail feathers as the core. This wand, made by the famous wandmaker Garrick Ollivander, has a special connection to Voldemort's wand (made of ebony and dragon heartstrings), because they both come from the same phoenix tail feather. Harry's wand was about eleven inches long, and it was elastic, which made it very sensitive and accurate when it worked. This wand was very important to Harry, and it played a vital role in his fight against the Dark Arts.
