I think it would be a (potentially big) waste of chainspace…
Ok finally have some results from this.
The proposal to shift from minimal encodings to 8 byte encodings for ScriptNums would result in roughly 1,176,417,034 (~1GB) larger blockchain. My current local blockchain size is
du -sh ~/.bitcoin/blocks
576G /home/chris/.bitcoin/blocks
This means this proposal would increase the blockchain size by is 0.17% since the genesis block.
I can share my json file used to calculate these, its large (13GB). Here is an example of a few txs, along with a link to my source code for calculating these json values

I’m working on testnet3 results, i’ll edit those in when I’m done with them.
