Yes it's entirely feasible, but be warned that it's a bit like working through a toilet seat with the engine still in the car
I honed the block on a friend's Ulster rep by doing just that, except I pulled the pistons & rods out to inspect the bearings as the car was a brand new unknown quantity in his life. Successive previous owners had tried all sorts to fix oiling plugs & all threw in the towel. In this case it was highly glazed bores due to wrong firing order & a hopelessly over rich SU. Bottom end was excellent, so I put the rods & pistons back in their original positions. We did a bunch of other stuff to the car from brakes to steering arms & track rod as well as re-shaping the clutch & brake pedals to suit the lowered seating position. Had to re-weld the exhaust manifold as well
Diagnosis was spot on, he went from oiling up new plugs within half a mile to a full day of belting it up the hill at Simola 3 weeks later & he's done several hundred miles since.
Probably worth it to give the bores a light hone while the block is off & you will likely want to discard the tin oil cups as they are not really necessary and a swine to position when dropping a block onto an engine in a car. Good time to go with a silicone block gasket from one of the cherished suppliers.
Plus he's my main opposition at the hill climb....
