If it were me I'd let Smith and Zapatas start chucking away (within reason). You're already making about 40% of your 3's, but your 3PA is, what, 3% of your total FGA?
If nothing else, opposing coaches will know that they never have to defend the perimeter against your team. Your next opponents' starting SG is a dud on defense - maybe match up Zapatas against him (looks like you'll need his defense on Freund anyway).
Disclaimer: I don't even have a full season under my belt, so it's probably best to ignore me. Good luck, I'll be watching and learning.
