I'm not a holder of any of those 3 but I would say the 3 communities need to collectively donate BTC to an escrow and use that to hire a competent dev to combine the premises of all 3 coins into one solid, stable wallet of a new coin which could perhaps start with 50% or so PoW coins premined and exchange those against useless LOL, CSO and ESC coins in fair ratios. Just an idea.
