Projector Screen and projector lift

[Dils]

Need some ideas on controlling projector screen and projector lift.
I have got
Projector screen – mains, with a RF remote, and a control box with Up, down, stop button these are on a circuit board (plan is to connect comfort outputs to switches)
Projector lift is custom made running @ 240v which I plan to control with CBUS blind relay with a delay on projector lift closing to allow the projector lamp to cool down.
I have UCM\\CBUS2 and RIO with IR
And I want to control this with IR, to send IR signals via Logitech Harmony 900 remote.
Would all this be possible, will I be able to connect the outputs from comfort to push buttons on projector screen control box. Or am I likely to blow something up. Or as a second option I can get another CBUS blind relay for the screen and just remove the control box.
Not sure how to do the responses, have one for open and one for close linked to different IR commands.
Any help would be appreciated

The Harmony remote control is able to send Comfort IR codes
The Comfort IR codes are received by keypads or IR receiver conected to RIO and they activate Recieved IR Responses
The Responses can be programmed to set or clear or pulse any Comfort Output

I am not sure if that is what you are attempting but if so then it is certainly possible
