Searching for an improvement for trash hands that would let them be more playable is a normal thing. I tried to do that many times. I think sooner or later most players will sometimes get tired of getting an unplayable sequences of weak hole cards. And these can last long sometimes in NLHE. I think that's the main reason Short Deck Poker was created and promoted. And all the Zoom and Fast Fold online tables also.
I won't refer to the rules you have suggested, because I'm not sure if I understood them correctly. I suppose it's about getting 50% money back when playing weak hands, but this might be a too powerful advantage for these.
I personally found a perfect solution for boring sequences in NLHE - it's playing "Hard Rock Casino" (2007) on Playstation 2. Old game, but it has the best poker AI I ever played and it's so difficult to win a 360 players MTT in this game. The cash games are easy, but MTT's really require skills to finish 1st. It really teaches a lot about poker and what's most important you can fast forward all the hands you folded, so you don't have to wait and you can play super fast
I definitely recommend this rare jewel to everyone who is bored with waiting long in NLHE for a good hand and constantly hungry for action.
