Welder Help

[Homicide13]

So, I started building a quite angular maze with the mansionbase wall02 walls, and when I went to go put welders at all of the corners and whatnot, I noticed that there was no completely round mansionbase welder. The two options I have explored so far are in pictures attached below, but both of them have problems. The first option looks good except for the little spaces at the bottom (what I did for this was I took one of the concave welders and just duplicated it and rotated it so the result was round). The second option is the mansionbase pillar, which is a little off-color and the shape makes it seem out of place.

Anyways I would like input /any possible solutions to this problem. I don't want the mood of the story ruined by a crappy setting.

In my opinion, the second option would be fine if the models could be re-colored to match the color of the wood panels, but I am completely clueless when it comes to modeling and texturing. (if anybody could help me out with this that would be great.)
