c7.5 - mimicking track stacks?

I haven’t had a chance to play with v7.5 but the specs, and the instrument rack in particular made me wonder-- can you send midi data using midi sends to other instrument rack vsti’s? and furthermore, could you save a bunch of vsti channels into a single track preset, and use a midi send from a midi part to send midi data to the remaining vsti’s, effectively approximating logic’s new stacked instruments feature?

No midi sends in instrument tracks.

but aren’t you using traditional midi tracks to access tracks in the new v7.5 instrument rack?
