... I don’t know if it is ethical to use someone else’s ideas

Not only ethical but is high praise

32519, in what way do Antonylee's objections re: interference over 1♥ not apply to your other nebulous openings? E.g. 1♠-(3♦), you will be the partnership who will do all the guessing at the table. Will you just rebid spades always as opener?

Others have also tried something different. Here are some of the more interesting systems I found in this forum:

I think you mean "interesting" as a compliment, but I wouldn't group a particularly strong system like IMPrecision with some bad (Pattern System or Galwood) systems or doubtful systems (Little Canape).
