I had some bespoke spacer adaptors made by Machine 7 in Nuneaton here on the mainland UK. I needed 924 to wide 5. Took a couple of weeks but very happy with the finished product. I guess 4 x 100 - 5 x 130mm spacer adaptors should be possible with about 25mm spacing (same as 4 x 130 - 5 x 130mm) All you need is the extra depth for the bolt heads to hold the adaptor to the disc/hub.
You just got to check the ET of the rims to see if they'll fit...
