Hm, I'm curious, how or where are you getting the data to reconstruct the Armory tx? If you haven't looked at their code, I think this approach is perilous, since Armory's custom format will surely throw your code in disarray.
For example, I'm not sure if the bytes from utxo's are appended like this:
for coin in inputs:
tx_list += get_raw_transaction(coin['txid'], json=False)
for byte in range(0,len(tx_list),80):
txdp.append(tx_list[byte:byte+80] )
, and, yes, at the code itself. These lines, in particular, are what I'm working off of:
