No, because drivechains don’t have their own native currency, they have a peg with Bitcoin and use bitcoins.

Is there not a a way to transfer their chains in without starting over?  Like Eth coverting to PoS?

Answering Objections to Drivechain

I would like to hear from the Monero and Bcash communities and find out if they would consider converting into a a Bitcoin sidechain if DC was adopted.  If they were enthusiastic and willing to convert then it would shed a more favorable light on these discussions imo.
