After seeing some very interesting 159 puzzles, I thought of squaring the rule set, without knowing if it was actually possible... Turns out it is - and interestingly solvable ! Thanks a lot to all the testers from the Cracking the Cryptic discord channel who helped me improve (hopefully) the puzzle to this version.

==== RULES ====
Normal Sudoku rules apply.
159² rules :
- Digits in column 1 indicate the column in which the digit 1 appears in that row (e.g. if r4c1 is a 6, r4c6 is a 1). The same applies to columns 5 and 9, with the digits 5 and 9 respectively.
- Digits in row 1 indicate the row in which the digit 1 appears in that column (e.g. if r1c4 is a 6, r6c4 is a 1). The same applies to rows 5 and 9, with the digits 5 and 9 respectively.
Little killers : Digits along marked diagonals sum to the indicated total (and can repeat, if allowed by other rules).
==== NOTE ====
If you are new to the usual 159 ruleset, I recommand checking one of these videos, or trying some of the puzzles featured in it :
159 Sudoku from the 2019 World Cup (quite approachable)

Loved how the puzzle unfolded. Wasn't too difficult, but wasn't a cake walk either. Great job, as always..
@XeonRisq : Thanks, for this comment, the solve, and the early testing ! I was aiming for difficult, but in the end I think this is the perfect right amount of tricky for this special ruleset, so I wholeheartedly agree.
