Sorry River still not finished the 2 tile but here is the 1 tile one for you at least.
You need move objects on to place them across the gap. I have fixed the mapping so that you can use a full pic:

and you can recolour them transparent:

When you open them to recolour them it doesn't show a texture it just says closed texture but just click ok and it loads it properly and you can then export the texture as normal. I have labelled the mesh texture for you.

To do a transparent recolour all I did was make a new transparent layer, and lowered the opacity of the texture, I think the one shown was set to about 55/60%, then added the rail and rings as a new solid layer and deleted the original png which was of course the bottom layer. I've put in the 2 recols so you can always export and use those pngs as guides or you can just bin them.
As it was made for you I'll not be releasing it anywhere (although obviously anyone can d/l it from this thread!) so just include the mesh with any recolours. (That goes for anyone else who d/l it from this thread, include the mesh with any recols for ease). I will get the 2 tile done asap for you. Figured you could have this to play with while waiting!!
