I agree that firing up a DAW and getting stuck into music making can be easier than using hardware. What if though, you had a dedicated small space with a minimal mixer and a small portable recorder elsewhere from the computer ? You could try out out different configs of hardware there and then perhaps let go of or decide to keep some of them. Sometimes nothing can stifle creativity more than a DAW and for me hardware is a great alternative.
I know how you feel about the kids one of mine has gone off to Uni and the place feels empty now
