l8orre, I just created a watch-only wallet with your address in electrum and tried several servers.
Some of them still had your transaction (and its parent) in their mempool and some of them had dropped your transaction from their mempool.

As mentioned by o_e_l_e_o above, you should be able to broadcast a new transaction using electrum.

If you imported your wallet and you saw your transaction, try different servers until you find a one that doesn't have your transaction in its mempool.
If your transaction status changed to local, right click on it and select "Remove".

In the case you connect to a server that doesn't have your transaction, you can broadcast your transaction even if the server's node hasn't enabled full RBF.
