Hextech Chests Skin Reroll Suggestion

Is there any chance of a rework in the pipeline to where rerolling multiple skins worth X amount of essence locks out the lowest tier (or 2nd lowest, etc.) from showing up in the result? For example, rerolling enough essence to entirely create a 1350 skin would lock out 520 RP skins, enough for a 1820 would lock out 750 RP, and enough for a 3250 RP skin would lock out 975 RP skins? Something to give some incentive to reroll rarer skin shards you dislike without the chance of, say, rerolling 2 1820 RP skins and a 975 RP skin and getting a 520 RP skin for one of the champions the 1820 RP skin was for.

Because currently any skin worth 975 RP + seems almost a waste to reroll, as the essence cost to reroll 3 decent skins is so high and the chance of a decent skin is so meh that rerolling high tier skins is almost always a trap.
