(RPL) percentage function % not preserving stack level 2

DUP is not double ENTER, it is just another name for a single ENTER. Not a big deal to hit it quickly twice
IMHO the RPN implementation of those %-functions is better done (more consistent) in RPL. LASTARG loads both operands in the stack pushing previous result up, which is AFAIC the desired way of doing it; with RPN you have first operand in Y - visible, the second in L - invisible and result in X. [X<>Y] & [LastX] (3 keystrokes) will be needed to mimic what LASTARG achieves with 2. On the other hand I have no clue how and what for you use them, so my views may not be applicable in your case, just sharing ideas.
