Get a single speed freewheel, screw it on, and see how it works.
It's a hybrid bike with long chain stays which will make it more tolerant to chain line.
The SS freewheel isn't as deep as the 7 speed freewheel. It won't screw on as far which will help with the chain line issue. Using the middle chain ring will help too. You might be able to mount the big chainring in the middle chainring position.
LooseScrews.com has freewheel spacers for Campy freewheels. If there were such a thing for Suntour freewheels you could simply replace some of the cogs with spacers.
