I believe deploying a HF after the Segwit update will be much smoother than doing it in this current condition.
Unfortunately SegWit is dead end of development, viewed by miners as a backdoor tool and enemy to decentralization.
I agree that everything would be so much easier with SegWit and Lightning Network.
But greedy miners won't allow it knowing that both these upgrades will kill their profits.
Bitcoin's entire security model is predicated on miners being "greedy". If miners being greedy is somehow bad then Bitcoin is fundamentally broken.
