Suggestion - Charged copper and gunpowder

So i wanted to make a suggestion to add some mechanics to copper.

CHARGED COPPER BLOCK

When a lighnting strike hits a copper rod, if there is a copper block (of any kind) under it, it will 'charge' the block.

In my head the charged copper would be kind of white depending of the weathered effect and you could uncharge it by rightclicking with gunpowder gaining charged gunpowder. if you don't want it you could always get rid of it and since gunpowder is quite common, it won't be that much of a waste.

CHARGED GUNPOWDER

with that powder, you could

craft a bit more powerfull tnt (charged tnt) - crafted with tnt in the middle and charged gunpowder on N, S, E, and W
craft a charged gunpowder block - crafted with 9 charged gunpowder

you could also obtain that powder by killing charged creepers

CHARGED GUNPOWDER BLOCK

would be used to power the copper rails instead of using redstone. That way the 100 blocks would be balanced since it's a bit of work to make it. And i was thinking that maybe it could be used as a light source too
