It seems there was an engine developed from the "B" engine through
another version ("O" ?). It was the Rover T16 and did go to 2.0L with
turbo....but would it drop into an MGB? Probably a little
difficult. It could put out 200bhp and some went to 800bhp (owwww!)
OK, to add to my original response ("No"), the O series did derive from
design studies on the old B series, but:
"By the autumn of 1972, the O-Series name was formally applied to the B-OHC,
and it marked the point in time when the final link with the original engine
was removed (..."the deletion of the "camshaft"/jackshaft so that the whole
B-Series tappet chest could be pared away"). The B-Series' design had acted
as a starting point, but no parts were shared - and this is demonstrated by
the cylinder block's light weight (due to the walls being thinned), meaning
that the strength of block could be braced in to the exact tolerance required.
This weight management would underpin the O-Series' transformation into the
M-Series during the 1980s."

The new engine did not even share bore, stroke, nor displacement with the
old engine. So no parts or dimensions were carried over. It was a new engine.
