Only if you buy two EMS units.
The number of potential customers for an Experimental EFIS with twin engine capability is probably a small handful, and they would not only have to change the software but also add a second input port for the additional sensors. Not likely to be worth their while.
An alternative would be to have two EMS D-10s for your EMS functions. Side by side they would only take up a small amount of space, and as dedicated units you wouldn't need to switch back and forth between displays.
Good luck!
