What's your idea?

Add the map Northern Italy by Ian D. Wilson to System18 for playtesting purposes. For the map, see https://boardgamegeek.com/thread/3238633/article/44685771#44685771

The rules specifics compared to the standard System18 rules are:
General:
• Partial cap, except use 2D stock chart with full cap share movement rules and special zones.
• Five majors.
• Extra tiles: grey tiles for Turin, Milan & OO, plus one each of #513 and #895. Also, two more #8 tiles.
• Remove tiles #12, #13, #205 & #206.
• 2-4 player. Start capital 480/320/240, cert limit 20/13/10.
• Trains: 52, 43, 34, 25(cost 450), 16, 18, unlimited D. 5 rusts 3 & D rusts 5 – brutal!
• The map is divided into four regions: Piedmont, Lombardy-Veneto, Tuscany and Emilia-Romagna.

Extras:
• Before each SR there is a PR (Parliament Round). In their turn, a player may start an (upwards) auction for the right to start a company in the subsequent SR. Minimum bid $0, bids in multiples of $5. (Use the charters to show the winners.) The round ends when all players pass. Winning bid money is paid to the Bank.
• The priority does not change during a PR.

Stock rounds:
• A player may only buy the presidents certificate of a company if they acquired the rights in the preceding PR.
• If a player does not buy the presidents certificate, the rights lapse at the end of the SR.

Operating rounds:
• Prior to phase 5, a company may not lay a token outside their home region.
• No half-pay, no double-jump, any payout to move right (as full cap rules).
• A company may, as its last action in the OR, issue its shares to the Pool. This drops the price down one space per share sold. This cannot be done on its first operating turn (except for EMR).
• EMR: issuing shares drops the price one space per share sold.
• If a player goes bankrupt, they drop out of the game with a score of zero, and the game continues. Their remaining assets are sold to the Pool (in this special case, presidencies and over 50% can be in the Pool); this money is given to the company in EMR and must be used to buy a train if possible.
• If bankruptcy causes another player to become director of the company in EMR, the new director must carry on with the EMR process.
• Cert limit does not change with a bankruptcy.

Ending the game:
• If no company is floated during the first stock round, then the game ends immediately at the end of that round.
• Game end is triggered by the purchase of the first D-train (not 8).

Are there related ideas?

I didn't find any other open issues on System18 maps. But the system is implemented with multiple maps (by Steve?). And there are several ideas for new maps, see https://docs.google.com/document/d/105S_1JeopE9Kc-oJhfe3dYt3Y8-5SKRCBW_8vPznBxs/edit
