The Enterprise E and TNG crew appearing sounds awesome.
Just don't like the idea of them getting blown up lol
It'd be nice to see the stylistic differences between eras.
Something like that should happen in a future film, with maybe even the TOS Enterprise next to the NuEnterprise
In this Alternate timeline, the TOS Enterprise being the one April had that got decommsioned earlier than it did in the prime timeline, to make way for the NuEnterprise.
