Cross use of Winwings EFIS/FCU and EFIS/MCP

Advice sought from anyone who has got/is getting Winwings EFIS or FCU/MCP devices. I’m trying to see if I can buy only one type of Winwings products. (cost reason and avoidance of having to change hardware to suit desired flying different types)

If I elected to buy the currently available Winwings Airbus type EFIS/FCU, could I use this (with SPAD.NeXt) for the 737/777 aircraft?

OR

If I bought the upcoming Boeing type EFIS/MCP, could I use this (with SPAD.NeXt) for the A320/330/350 families?

thanks anyone
