The D15-4 reload is nearly a perfect replacement for the D12-3. For the
E15-4, the E18-4 is the best choice for an RMS substitute -- both of
these fit the RMS 24/40 case, and will use the same 24 mm adapter you'd
use for the D12 and E15 single use motors. I might also mention that
the E30-4 and E28-4 will also work nicely. I'd avoid the E16; it's got
a bad reputation for slow thrust build up and bonus delays that have
trashed many an AT Initiator from a starter set. The E23-5 would be a
better choice if you don't have a 24/40 motor.
For the larger motors, the F52-8 is a good sub for the F50-9, but the
F40-7 will also work well, and the G64-10 will be the best sub for the
G40-10 (but beware of losing the rocket and case on this very high
flight). Again, the BJ propellant in the G33 is notorious for slow
starts; in addition, the G33 exceeds 62.5 g propellant, making it
technically an HPR motor requiring L1 cert and LEUP to buy and fly, and
LEUP and magazine to store, as well as requiring FAA notification even
if the liftoff mass of the rocket is under 454 g.
Some of their knowledge is corrupt, and inaccurate, being gleaned from
all manner of sources. But like us, they are wizards too.
