House Lannister Wand - Golden Rains
Hey Magnavis ! You need to contact J.K. Rowling/Warner Brothers and George R.R. Martin/HBO and get the ball rolling on this mash-up of yours!
GREAT IDEA! Both fan-wise and marketing-wise!
The only one I would revist is the "King of Winter" wand. It just looks too much like the "Longclaw" wand.
I really do think that in mass production these would sell like gang-busters in the $20-$30 range. I don't know what your share of the profits would be considering the wildly high cost of marketing between these two giant franchises, but even a buck a wand from a million wands nets you a million dollars!
In the 'limited production, I built these by hand in my basement with real wood, metal, hair, and Swarovski Crystals, with super-high-end finishing market' you could sell them for several hundreds to thousands of dollars. But you'd be targeting a very niche market of fans with deep pockets. You'd be very successful in that you might sell every one you're able to make, and you'd probably gain a bit of notoriety among both fan bases, but you simply wouldn't be selling the quantity that mass production can pump out at a much lower cost.
Either way, I wish you Great Luck on the completion of a GREAT IDEA!
