My friends and I ever played one Chu Shogi variant called 'Heisei Chu Shogi'.
http://pika.cs.nctu.edu.tw/lit/HeiseiChuShogi.rar
The description is as fallowing:
Heisei Chu Shogi, a variant of Chu Shogi, lets 8 kinds of relatively
weaker pieces get more opportunities to cooperate with power pieces
like Lion and Free-King. The rule is a transitional blend between
Chu Shogi and Modern Shogi.
All Copper General, Kylin, Lance, Side Mover, Silver General,
Phoenix, Reverse Chariot, and Vertical Mover are removed from the
borad and put aside in advance. Other pieces are still on the
original board setup of Chu Shogi.
Once during the game, a player may put his one of the removed pieces on an unoccupied square adjacent to any friendly piece as long as dropped piece can move. If dropped into the promotion zone, the piece may dropped as its promoted piece or promote on any subsequent move in the promotion zone.
For exemple, a Lance cannnot be dropped into the last rank; however, its promoted piece, White Horse, can be.
When captured, unlike Modern Shogi, the piece can't be dropped again. Other rules are as in Chu Shogi.
Another modern Dai Shogi variant is called Heisei Dai Shogi. It is like Heisei Chu Shogi owning Hand pieces, and has some special rules about captured pieces.

The rules are as following:
16 pieces are set aside at setup and held in reserve, and once during the game a player may drop one of these on an empty square adjacent to a friendly piece.
The set-aside pieces are the Lances, Knights, Coppers, Silvers, Side Movers, Vertical Movers, Reverse Chariots, Kyrin, and Phoenix.
If dropped into the promotion zone, the piece may dropped as its promoted piece or promote on any subsequent move in the promotion zone. As with dropped pieces in standard shogi, the piece may not be dropped on a square from where it cannot move.
For exemple, a Knight cannnot be dropped into the last two rank; however, its promoted piece, Gold General, can be. Captured pieces do not come back into play.
There are special rules about some pieces regarded as 'prize pieces.'
Except for King, Prince, Horned Falcon, and Soaring Eagle, other pieces capturing one of 'prize pieces' may become into Lion immediately or waite another occassion of capturing prize pieces.
The prize pieces are Angry Boars, Cat Swords, Evil Wolfs, Flying Dragons, Violent Ox, Iron, and Stone.
The rest of the game is played as in regular Dai.
