Putting this up front: I've only really read snippets of the responses here, at least enough to get a general understanding of where the community as a whole seems to stand on this change. I also don't have much experience with House Govs, with the majority of it coming from interactions with people who are part of Govs themselves.
If we're going by the direct wording here,
Liberty will have four representatives,
Rheinland and Bretonia will have three,
Kusari will have two,
and Gallia will be left with a sole rep to vote on laws.
Quite frankly, I don't really see this working all that well, no matter how 'regulated by staff' it is. There just aren't enough bodies voicing opinions, and in the case of Gallia there literally isn't any discussion whatsoever.
This also essentially means that it won't truly be the govs voting on approval or disapproval, but the staff, since they can veto any post made with House forum accounts. Sure, maybe this won't happen in practice, but it can happen, and that really doesn't sit well with me.
Expand it to the 1ic and 2ic of each faction involved, and maybe even expand it to factions that can enforce the house's laws without being lawful. This gives the UC/- some voice in matters that effect them, since they literally own an entire Gallic system, and even gives a Hogosha faction some voice in Kusari if someone finds the interest in making that grind to officialdom.
Otherwise, I really don't see this as being anything other than being doomed to failure from the get-go.
