I'm not sure I understand what you're trying to achieve.
Is there a reason you need to create L3 interfaces on the downstream stack as well as the upstream switch?
On Meraki switches, VLAN's are already present and tagged traffic can be passed by default. They do not need to be created on the switch as you would on a traditional Cisco switch via CLI.
If you already have a VLAN 104 interface on the upstream switch, you don't need to create one on the downstream stack. You would configure that upstream IP as the gateway for the VLAN.
If you have L3 interfaces for some VLANs (Eg, 1,3,5) on the downstream switch and L3 interfaces for other VLANs (2,4,6) on the upstream switch, then it makes sense to create a transit VLAN between the two switches.
I have a stack of two MS425 switches that I may use for top of rack purposes. I wanted to create two separate VLANs for iSCSI traffic. They will not be routed out of this stack, but I would still need to define VLANs for them.
If the traffic is not being routed, an L3 VLAN interface shouldn't really be needed (unless you have some other requirement for it). You also don't need to explicitly define the VLAN anywhere like you would in traditional switches.
