Running a Mini Split to Ducted system

I am working on a home expansion and have the opportunity to upcycle a large Mistsubishi heat pump that will cover all of the needs for the property.
The main level currently has a Lennox compressor and air handler. More capacity will be available to the air handler.
Will it be possible to adapt the Mitsubishi to the ducted system.
I will then have three upcycled mini split air handlers to use in the attic addition. And the garage.
Any help would be greatly appreciated.

Your question is lacking in specifics on exactly what the Mitsubishi system you want to reuse exactly is. Without knowing more, if this is a standard multi-split system, adapting it to a conventional split system ducting system will not work. I just installed my first ducted multi-split system but they are not designed to be ducted like a standard branched forced air system. I could conceive of how something like you want to do could theoretically be done, but reengineering the equipment would be make a Frankenstein of a system that would be a maintenance nightmare that no one would touch.
