Using an empty filter ring as a spacer sounds like a good idea, and not very expensive. Only actual testing will tell you if it vignettes or not.

The simplest solution probably is to obtain any type of not expensive, broken, scratched, or used old filter with 95 mm tread ( you need just one), remove the glass and use metal part as an extension ring. Cokin actually produced that type of extension rings with the same diameter for in and out tread, but just only a few sizes. Check if they have 95mm. And last thing to order the custom made transition ring, and here you can find a person who can made it for you not very expensive http://www.largeformatphotography.in...r-lens-flanges .
In a sense vignetting is always what limits your movements. Assuming no bellows sag, you'll always lose the corners first with extreme movements because the lens itself eventually vignettes (or goes soft, depending on the lens design). So yes, a spacer will cause you to lose corners sooner, but whether it's an issue depends on what format you're using and what you're doing. The 150SSXL covers 386mm so you've got a decent amount of movement on 8x10 and might not notice the loss unless you do architectural or other work that requires a lot of movements at infinity. I can't see it being an issue on anything smaller than 8x10.
If you can find a junk filter just try it and see. At worst you'll be out small money. I'll be happy to buy the spacer ring from you if you don't want it.

I recommend also replacing the lens caps with S. K. Grimes lens caps. The Schneider front lens cap can contact the lens element.
The 110mm SSXL has a similar problem of the highest area of the front element not clearing some tread on fiters.
One of the easier ways to deal with this problem is to put a 95mm to 105mm or 122mm step ring between the SSXL front to larger filter.
Or use a much larger square filter system or Sinar 103mm glass filter system.
This is a really excellent modern wide angle lens that covers 8x10 with ease as a wide angle or moderate wide angle on 5x7, definitely a keeper.
