Inquiry About MEC Configuration with Stackwise Setup

Hello,
I'm planning a network setup as shown in the diagram, where SW1-SW2 and SW3-SW4 are configured using Stackwise.
In this setup, I intend to connect SW1 to SW3 and SW2 to SW4, and configure MEC (Multichassis EtherChannel) accordingly.
I'd like to ask if this configuration is supported and will work as intended.

Thank you in advance.

Believe both Stackwise or Stackwise Virtual would support.

As to working as intended, what's intended?  (That's not a frivolous question.)

Oh, it's nothing else — I just wanted to ask if MEC configuration is possible in this setup, where SW1 is connected to SW3 and SW2 is connected to SW4

Ok, then again, it should be for Stackwise (or Stackwise Virtual).

Just curious, are you new to this technology, or is there some reason you thought it wouldn't work?

It support

MEC of domain A will use for example 

Port Te1/0/1 and Te 2/0/1 as part from PO 100

This PO 100 connect to domain B ports Te1/0/1 and Te2/0/1

PO 100 can be 

L2 and you using svi of vlan assign to PO to connect both domain 

L3 (no switchport) and have IP from subnet/30
