Yes. You might want to consider using the stronger MGB diaphragm clutch,
though. If you do that you should use the MGB flywheel (different bolt
pattern - saves redrilling the Riley flywheel) and front trans cover with
throw-out arm and bearing (different height on the pressure plate), and check
for interference of the pressure plate in the bellhousing - a bit of
judicious grinding may or may not be needed.
Other than also swapping the front plate, is

You mean other than the fact that you have exceeded the strength of the weak
rear axle by an even bigger margin than the 1500 did? You might want to be on
the lookout for a replacement B series axle (I know - then you have 2
different bolt patterns front and rear). The kicker is that only the MG
Maggot has a wide enough axle. Or drive very gently!
With the more powerful engine, a disc brake conversion using Spridget bits
makes a LOT of sense. Do all that and you'll have a really nice little bomb!
