There's an old idea that solves the storage issue completely - utxo commitments.

Literally the only real throughput limit is end user's download bandwidth, which means 500MB blocks or so for 10Mbps download. Spv clients are fine for those unfortunate to have monthly limits.

Both storage and bandwidth are utterly insignificant cost items in a mining operation.
