I think you could join then up, I joined up 2 cables to get the right length for my laptop to TV connection.
buy them at a store that has an easy return policy just in case and give it a try.
only possible thing is the very cheep cables and connectors are usually lower quality products.
but for light or occasional use they should work fine.
