Hi community.
I have 02 Aruba 8400 in a VSX deployment (let´s call them SWC01-Primary and SWC02-Secondary)
I also have 01 Aruba 3810M switch (let´s call it SRV-SWITCH) that has an important server connected to it.
Port A1 on SRV-SWITCH is connected to port 1/9/32 on SWC01-Primary
SWC01-Primary has lag 40 multi-chassis with port 1/9/32 assigned to it. This port 1/9/32 has a 10GE-SR transceiver installed and working
SWC02-Secondary has lag 40 multi-chassis with port 1/9/32 assigned to it. This port 1/9/32 has no transceiver installed.
SRV-SWITCH has a "trk1" lacp group with ports A1 and A2 assigned. Only port A1 has a 10GE-SR transceiver installed and working, A2 has no transceiver installed.
Configurations on my switches are the following:

For this deployment I want to release the 10GE-SR transceivers that belongs to both ends of the link between SWC01-Primary and SRV-SWITCH for another use, without disrrupting the server installed on the Aruba 3810 named "SRV-SWITCH".
For this purpose, I want to use a 3m DAC cable (J9283D) and connect it to port A2 in SRV-SWITCH and port 1/9/32 on SWC02-Secondary.
Questions:
In this situation, will the interface "lag 40 multi-chassis" bundle port 1/9/32 on SWC01-Primary and port 1/9/32 on SWC02-Secondary to become a 20 Gbps virtual interface?
In this situation, will the trunk "trk1 lacp" bundle port A1 and A2 on SRV-SWITCH to become a 20 Gbps virtual interface?
Will a link aggregation group conformed by a 10GE-SR fiber optic link and a DAC cable link work correctly?
If this works, this will allow me to create a mixed link aggregation group (10GE-SR link + 10GE DAC cable), then replace the original 10GE-SR link with another 3m DAC cable (J9283D), releasing the 10GE-SR transceivers, all without disrrupting the server operation.
Have anybody deployed this kind of mixed link aggregation group?
Tnaks in advance for your support
