I feel this would be a great way to counter RMTs main source of income, whilst still benefiting legit gatherers. I've just knocked out my 3rd 50 DoH tonight and aside from the occasional jump to mine some nodes when prices sometimes spiked I just bought my shards off the market, a couple of times I've derped a touch and typed in crystal rather than shard - the prices were so similar per unit that I almost ended up buying 1-3k crystals instead of shards! I feel that if a system such as the above isn't adopted, then perhaps change lvl 40+ recipes that use 4-5 shards to use a single crystal, that way you bring some value to crystals whilst also driving demand for shards down.
