Yes, you can always replace CSV with CLTV. The downside is that if something goes wrong with channel negotiation you need to wait for much longer, and you need to reopen the channel fairly regularly (which has its own problems, since you can't accept a HTLC which passes your CLTV timeout, so you probably want overlapping channels). I am really hoping that OP_CSV gets deployed in time to avoid such a hack. There's plenty of work in the mean time! Cheers, Rusty.
