Just a thought , 7" is pretty much standard for lute backed instruments but it's worth considering a smaller wheel - say 6" which is more the norm for Guitar bodied gurdies. The smaller wheel makes no difference to articulation of trompette ( imho ) . The slower rim speed helps to minimise the unpleasant resonances that can occur and the overall volume is slightly less. A 6" wheel may also be a more practical size for those with only access to a small lathe. I use an average of 16mm for rim width and 18mm rim to bridge.
