Hi Diki,I completely agree on your solution.
The
Kawai VPC1 88-key Controller with the superb RM3 Grand Wooden Key Piano Action is designed for this scenario. It is heavy though at 65lbs.

David Ahlund.

https://www.sweetwater.com/store/detail/FantomEX8--roland-fantom-8-ex-synthesizer-workstationThis strategy is similar to introducing the Roland RD-88 as a portable version of the Roland RD-2000.
The Roland V-Stage Piano uses the same PHA-4 action as the RD-88.
If someone just wants a portable Piano for gigging they would chose the RD-88.
On the other hand if someone needs the Organ, Electric Piano and 2 Synth Voices layered on top with hands on controls, they would go for the Roland V-Stage Piano.
It is in direct competition to the NORD, but at a lower price point. The market will decide the winner.
