I shared my thoughts in the comments on the other post but will echo a similar sentiment here.
I definitely think this is an interesting idea. There is a long history of collaboration between the ICL and various Neutron contributors. I also think Neutron provides a great ecosystem out of the box that is primarily held back by liquidity (not apps).
That said the technical and social lift of doing this right would make it nearly impossible to do this in an efficient way. Both the ICL and Neutron have been setting exciting next steps (post-ICS) and it would be unfortunate if these were slowed down and not given room to breath. As a result, I think the two chains should stay sovereign for the time being, and in the mean time explore collaborations to see how they evolve overtime.
Definitely appreciate your thoughts though @Guinch_Roze and my mind is open to being change by you and others.
