Your variant is not. Additionally, there are several cards which would severely impact this practice. Summon, Villa, Port, and Lost City (just to name four), can greatly impact how your turns go, and by not allowing the second player to react to the first player buying one of these cards, you're reducing their ability to play (especially in the case of Lost City, since they might have a different amount of money).
I'm not sure you read the OP all the way through... My suggestion for SI was better than the "write down & simultaneous reveal". Write-Down is what I currently play with my brother, and it has it's own limitations, of which you mentioned a couple.
But my focus in this thread is Blind-Reveal... which is essentially like playing your first 2 turns normally, other than that most of the information about what you do is obscured from your opponent. In Blind-Reveal, all cards would behave normally. It's the information that is hidden, to the extent that that's possible. I tried to list all the cards in my OP that functionally couldn't be kept secret, and I'll address the cards you brought up in that context:
Summon - If an interactive card, like Sea Hag, is purchased with Summon on Turn 1, it would have to affect Player 2, and thus it wouldn't be a secret. Thanks for mentioning it. I missed that one in my list in the OP.
Villa - No problem playing this one with Blind-Reveal. You buy it and bounce back to your action phase, but it doesn't affect your opponents any. They find out on turn 3 what you did.
Port - No problem playing this one with Blind-Reveal. You get 2 ports. They find out on turn 3.
Lost City - Mentioned in the OP as one of the cards that gives itself away with Blind-Reveal. When you buy a Lost City, I draw a card, and thus can deduce what you purchased.
