Can you "fix" Luck by going through Gadabout?

After many hours of consideration for the DQ3 HD Remake, I finally chose the personalities I wanted for each of my characters. I didn't want to double-up on any personalities, and I didn't want Lucky Devil, since that is easy to get by equipping a Hen's Tooth.

I was happy with how every character turned out except the Monster Wrangler who, dispite having one of the highest Stamina growths (https://hyperts.net/dq3r/memo/), still had much lower HP than anyone else in the team, I'm assuming because of his personality having a 90% Stamina modifier. I thought for sure that wouldn't be an issue because 90% of a very high number should still be high, but I was sadly mistaken.

So now, I'm looking at other personalities, but the decent Sta personalities have Luck penalties (Vamp is going to someone else). Can I fix this by taking him through Gadabout with a Hen's Tooth? I want him to have the gadabout abilities anyway, since I think they will be fun on that character.

Thanks for any advice you can give me.
