I did - see Printing the ekech 6x12 RFH - it is what I used in one of the pictures above. I find the film advance can be a little tight, and easier to do off-camera, but it works. The true manufactured roll-film holders are much nicer, but a Cambo slide-in 6x12 was over $900 used last time I saw one. The Widepan seems to be $600+, and it resembles the Horseman which will not go in the Wista back easily.
I put a commercial ground glass in the Wista back - I'll probably use it with the Will Travel as well - which is better than the acrylic one, but not as good as the original Wista glass. That cost about five times the cost of making the back excluding my time. I expect I'll write it up for my web site at some point.
