Purchasable Player Warps in Petal Shop

It'd be nice to have the chance to get player warps without a rank (or more player warps as a ranked player) with petals from the petal shop. Maybe an increased overall limit of 8 (4 obtainable from shop, 4 obtainable from ranks) or something like that would be great. Not sure about the cost; maybe a flat 1000 petals per warp or an incrementing cost starting at 500 petals would be a good place to start.
