I guessed someone had already stumbled upon this since it is quite old but you really went beyond
It would have been awesome if you managed to realise your idea but as you said it would be (and still is) way too expensive to do it...pity
But overall nice twist to the original design of the swords by Fable Blades especially with Anduril... I like it very much.
Also the dark red leather grip for Boromir's sword makes sence to me since it would go well with his tunic and shield.
As for Strider's sword, the runes engraving on the fuller is an interesting idea as it would place it in the company of Anduril and Sting who have been decorated additionally ("historically") after important events and experiences.
Of course, I love the original designs from the movies and wouldn't want them changed but I like these creative twists
