Hi scimjim, if you want to stay with standard Triumph wheels, you could go the route I have gone.
I used basic Triumph solid disc wheels, drilled out all the holes, and the finished product fills out the wheel arches and I think, looks quite presentable.
The biggest drawback is that theses wheels in 5.5J form are hard to find these days, I was lucky enough to have hoarded them for years!
Take look at the following pics.
