mix & match pattern pieces?

First, since I am a senior citizen, it's taking me a bit of work to get my head around the idea that people are out there trying to help me during the covid-19 troubles (when a neighbor I trust showed up at the door with fresh French bread, first I couldn't figure out why he thought I'd need help--then I cried to realize his generosity, since he was "reaching out to seniors who are shut-in during the crisis!). So, since I'm supposed to stay in, and I want to help, I thought I'd start by sending my prayers to anyone reading this. Now my question is this: After trying several brands and not finding any patterns that didn't need a lot of alteration to fit me, I was delighted to discover that Liesl's classic shirt came out great (thank you to the [person who helped me understand that pattern). Now the hot weather is on the way (AZ gets REALLY HOT!), I'd like to make a shirt in short sleeves. I have a pattern with short sleeves that doesn't fit in the body as well as Leisl classic, but like that one, it has a single yoke back and button front. This might sound like a really dumb question, but would it come out ok if I just took the sleeve pieces from the pattern that doesn't fit me in the body so well and exchanged them for the long sleeves in the Liesl classic shirt? Thank you! edb
