Yes, a sleeve should seal that up no problem.
I sleeved a 454 chevy that had a huge gaping hole in a cylinder wall. Used a .125" thick sleeve w/ around .0015" press fit and a lot of green Loctite. Heat the block, freeze the sleeve, and knock her home w/ an old shortened axle shaft. Still running good in an old tow truck.
