Thanks for the question. You could certainly try playing the open first string.
Only downside is it would make the right hand picking pattern a little trickier. That’s why I didn’t write it that way.
You’d have two notes in a row on the first string if you used the open first string in 27.
But I’m sure with some practice you could figure out a picking pattern that would work for that. You could try bringing your thumb of your right hand up to play the open first string. Then keep the rest of the right hand fingering as written.
It’s totally fine to make adjustments to the tab though to fit your particular needs!
Let me know if that helps.
