Perhaps MC should use the Eternal Fire, the Reality, Power, and Space stones in a Ritual to remold his Divinity, Magic and his body. The Eternal Fire is in Asgard, the Space Stone is in Norway. The other two can be tracked with the Space Stone and use illusions to replace the power stone in the Nova Empire. The energy from the stones and the flame should be better than vita rays and might give him reality warping powers especially if Ms Death contributes.
And MC should also learn crafting from the Dwarfs. He can claim that he would only use a blade that has been forged by himself. A good answer if Odin should ask. And if the Dwarfs refuse, tell them their fates and how their entire civilization is bound to be destroyed, promise to save as many of them as he can when the time comes for all that they know about crafting, forging and building.
i dont know how strong is mcu odin to be honest, i think you should base on comic books and then divide that to its maximum so it can fit in mcu, maybe capable of universal destruction but only with odin force at his maximum power and with a lot of troubles, like diying after that or loose 95% of his life spawn something like that, about the tons he can lift i dont know make it 500 or 1000 is not that crazy to lift the world or destroy the moon, but is strong enough to make sense with your power classification, odin is still one of the most powerfulls in every marvel universe
