Upside Down Chess as a variant?

@AHappyCactus we could give some black compensation. For example, if you take the Sicilian, white has more space at first and more pieces developed, but black has compensation in the fact that he will have a better endgame and a more safe king.
@TCF_Namelecc I just want to point out that Stockfish evaluation value of starting position in this variant may be absolutely off/irrelevant here for several reasons.

1. Stockfish is programmed for standard chess, meaning relative piece values are tuned to death for standard chess where you have only one queen in opening phase and sometimes 2 in rare endgames. In this variant you have lots of queens in the opening, causing it clearly has different relative value here. Same for other pieces.

2. Humans are not machines. Even top GMs cant play variants on engine level. I mean lots of unbalanced variants (by engine eval) are playable by humans. Just look at antichess, atomic, zh!

3. White Win vs Black Win rates:
54% vs 45% in latest huge upside down tournament lichess.org/tournament/teSmrRnx
54% vs 43% in Atomic Shield Arena lichess.org/tournament/Gxv583E6
Last I looked, FICS still supported it(wild/5 there) but nobody was playing it. Although the same is true of antichess(suicide chess on FICS) so maybe people would play it here?
#1 I've suggested this before... it seems unlikely at this time, sorry.
Also, since the rules are the same as chess, it would be possible to use "play from position" to play this variant. Although it wouldn't work well for rated games, it should work for casual.
