Move series / multimove idea to speed up large board chess games

While playing a chess variant on a very large board, or a large Shogi variant, we could consider to allow more moves in one turn, in a way that does not have the awfull inbalance and complexity of Progressive Chess.

What I here propose is that a series of moves is allowed under these conditions:
- No move within the series introduces a new attack on an enemy piece (including check on the enemy King)
- No move within the series resolves a current attack on a friendly piece (including resolving check on the own King)
- No move within the series captures an enemy piece
- No move within the series induces a special influence on an enemy piece (like freezing a piece, making something transparent, if such pieces participate in the game)
- No move within the series removes a special influence from an enemy piece on an own piece
- The series of moves is done within the time control for one move
- Perhaps, but not necessarily, the series are bound to some maximum number of moves.

Example

White to move, pawns can advance 4 squares on the first move.

A legal series for white would be:
g7, h7, i7, j7, Di3, Di4, Di5, Di6

What is the rationale for this idea?

Some maneuvers take a lot of moves but execute singular ideas.
I want to advance all my pawns.
I have some slow stepper and I want to get it in the center.

So now these things can get accomplished quickly and games can develop faster.

Where could we use this?

Thoughts?

but can't the other side utilise this and change their plan though

I included the condition "No single piece is moved twice or more often during the series" but my example has the Dwarf doing 4 moves within one series. I'll rethink that part.

Yes, what's the point in that?

There's no good reason to include this condition.
