It’s a tricky chess game we have here, let’s get mathematical for a sec :
We have the Dark Trinity, the Digi Trinity and the Model Duology.
If the Dark Trinity = the Digi Trinity,
then :
A4 = DN
AR = ST
OT = DT
-> The AR got the sample engine of the DT (the DT does not overlap with the OT)
-> The ST got the synth engines of the M:C (the M:C does not overlap with the DN)
so, we have :
(AR x DT) / OT
(ST x M:C) / DN
If we want the ST to have a sample engine, it must not overlap with the DT, so it might have the sample engine of the M:S, then :
√M:S ((ST x MC) / DN) = ST²
BUT
if ST², then the equilibrium of the two Trinities would be compromise, because there is no AR², so if we want ST², it should be ST² = AR²
to have AR², the AR should have the synth engine of the DN, so it should go like this :
√DN ((AR x DT) / OT) = AR²
and then √DN ((AR x DT) / OT) = √M:S ((ST x MC) / DN)
the equilibrium of the two Trinities is restored.
To sum up, it’s a big thing to add a sample engine to the ST.
Oh, by the way, I hate maths.
