James,
A lot of these fiddle tunes can be played various ways. Especially the little connecting phrases.
If it sounds better to you to play it the way you mentioned that’s totally fine. The phrase I did way just a little “melodic” run but an open roll would work just fine as well.
The open roll would definitely work well if the song was played faster as it would give you that extra little time to get back down for the C chord.
I’m glad you’re experimenting and finding out what sounds best to you.
