1/2 to 3/8 reducer on chrome lavatory/toilet supplies ok?

I am installing a new pedestal sink and toilet in our guest bathroom.

I ordered the kohler chrome angle supplies listed as compatible with the sink and toilet on the vendor's website.

Unfortunately, I neglected to note that there were 3/8 and 1/2 inch versions available. (and I'm only assuming they all come in alternate sizes, haven't been able to track down a p/n for the toilet supply in 1/2 yet) Of course, when I went to attach the stops, I realized they weren't going to work.

Any foul in simply using 3/8 to 1/2 reducers to make 'em all fit?

You could use the reducer but it will look kinda goofy and stick out.
