The (potential) Wedding Gift re-gifting
I recently re-watched The Wedding Gift Wormhole. In the episode Sheldon and Amy have received a crystal wand as a wedding gift from Leonard and Penny, who in their card called it "the perfect present for the perfect couple." Shamy spend most of the episode trying to figure out the meaning of the gift, eventually pursuing a scavenger hunt they believe Leonard and Penny set up for them. Meanwhile we learn the crystal wand was something Leonard and Penny were re-gifting from when Howard and Bernadette gave it to them for their wedding, and that Raj originally gave the crystal *chakra* wand to Howard and Bernadette for *their* wedding. Raj clearly doesn't appreciate Howard's re-gifting.
Towards the end of the episode Raj reveals that his dad organized an arranged marriage for him and that if things go okay, he'll be getting married soon. Sheldon makes the statement that he and Amy know what to gift Raj for his wedding.
I think the intended joke was that they'd gift the crystal wand to Raj, effectively giving him back a present he first gave Howard, that had made it around the entire group. And as a joke that's funny, as it would probably frustrate Raj.
But I don't think that's what Shamy would do. Shamy absolutely loved the scavenger hunt they believed Leonard and Penny purposefully organized for them. So much so that they created a puzzle for Leonard and Penny themselves to solve, thinking it would bring them similar joy. I bet Shamy would go to great lengths to make a very intricate scavenger hunt for Raj and his wife as their wedding gift. And given how Raj has been shown to enjoy organizing similar things for his friends himself, I honestly bet he'd love that wedding present. He might be the only other one out of the group who would, but it sounds pretty perfect for him.
Also, given Sheldon's strict adherence to the social rules around gifting, I don't really think Shamy would gift Raj the crystal wand at all - I think they'd come up with their own first clue present. So Raj wouldn't end up irritated getting his original gift back and he'd get to experience an awesome scavenger hunt like the one he sent his friends on in The Scavenger Vortex. Honestly his end message in that hunt even mirrors the one Shamy believe they got from this episode and clearly intend to replicate for Raj.
It would mean the wand would never come full circle, but I bet it would be a great scavenger hunt.
