well, this is going to be fun. electrum 1.9.8 doenst have replace fees.
Being originally from a paper-wallet and with no change address' showing any amounts, can i just close down electrum and fire-up bitcore to import the same paper-wallet key and do a refee or cancel from there? If it was an electron created wallet or had change on it the process would be different.
im pretyy sure i can do this and may just go ahead before an reply. bc's all sync'd redy to go, one must be able to import and export different wallets
first of all: it might be a good idear to update your wallets from time to time

With electrum, as long as you have the seed phrase (for a hd wallet) or the private keys you imported originally, not much can go wrong...
As for your question: i don't really follow what's happening at your end, but, generally speaking, you can import private keys from a paper wallet into as many desktop wallets as you want. As long as you don't spend the unspent outputs by creating a transaction and signing it using the private key from your paper wallet, each of those desktop wallets has the potential to spend the unspend outputs (wow, that's a confusing sentence

)
In the end, it might be more usefull to use viabtc's txaccelerator, and just wait untill they hit their next block... Your transaction had a 58 sat/byte fee, so if you submit it to viabtc exactly when the next hour begins, they should accept your transaction, and it should be confirmed in a couple of hours
